>> appreciate the status, thank you. the next hour of cnn newsroom starts now. >> thanks for joining me on this christmas eve. i'm erika hill. we're following two big stories today, brand new warnings from the fbi and homeland security over possible threats from isis. they say that terror group might target churches and other holiday event ds. this of course as millions of americans prep to celebrate the biggest christian holiday. and new arrest in the christmas market attack in berlin. three men in custody accused of having ties to the man behind that grew some attack. we want to start first with that new warning about possible deletes here at home. cnn sandoval following the

story. what do we know about the warning and where it came from? >>. >> reporter: brand newly issued bulletin, no credible specific threats against any target in the u.s. that being said it is recommended that law enforcement officials remain on high alert because of this isis friendly, this pro isis website that has initially called on some of its supporters and isis sympathizers top launch attacks or carry out attacks at churches or houses of worship across the country. the reason this is being issued, to answer your second question is because they noticed on a website, on this pro isis web page we mentioned, it lays out a list of several of these churches and places of worship. so as a result they are being proactive, officials are. then there is that lingering question this is not like anyone else we've seen. typically they're directed more toward law enforcement or military targets.

these are the softer targets. the question is why. we heard this morning, a republican who sits on the house homeland security committee, offering his take why we could be seeing this kind of threat. >> isis wants to spread fear, primarily by inspiring homegrown terrorism through the internet, through the dark spaces of the internet and get people to rise up and create attacks of terrorism when fr possible. we saw at the pulse nightclub for example, they're doing it now with respect to the holidays. they're trying to inspire people and hope that someone picks up that -- is inspired. like we saw in germany. >>ing this is happening after the deadly attack at the christmas market overseas and happening as millions of americans get ready to celebrate christmas and han ka.

officials want to stress don't necessarily be afraid but be on high alert. this is a proactive step as so many people now head to celebrate the holidays with their families. >> po la sandoval, appreciate it, thank you. for a closer look at this delete, former cia director and adviser to the trump complain. good to you have with us. when you look at the threat, how serious is this? >> well i think it's quite serious and kudos to the bureau and the homeland security and the other law enforcement people who are starting now to look at sources to look at the websites, to try to get inside the heads of the terrorists and where there may be heading rather than waiting until the last minute and catching them after they've done something. this is a step in the right direction. the terrorists, the muslim

terrorists love anniversary, had he go after people at the boston marathon on the anniversary of the beginning of our revolution near war. they use anniversaries are big for them. so christmas, of course, is going to be a time when they are going to focus on trying to move us into one of two statuses that they want. they either want us dead or converted. and there are -- there is no third possibility. and they are at war with us. we're not at war with them. we are kind of thinking about it. but they're at war with us and we have to get inside their heads the way you would any enemy that you were fighting and figure out how to keep him from moving further along toward harming you or destroying you. >> in term of getting inside their head, i know donald trump made it clear that defeating isis is at the top of his list.

you said we have to go after isis in their own backyard, as you said get inside their heads. we are recognizing, i think perhaps it's being reinforced with every attack we see, especially on these soft targets, this is a really large backyard. we look at the fact that the recruitment network that amri was apparently associated with in germany was supposed to focus on recruiting in germany. where would your advice be for donald trump, where should he focus his efforts today based on what we have seen in the last 24, 48 hours? >> first of all, not to follow through with president obama's decision to admit thousands more people before we have extremely thorough vetting. i think we have to -- we're a nation of immigrants and we want to be welcome to immigrants. but we have a very difficult situation now with isis and we have to protect ourselves. and we have to understand that we are at war and we have to

stop them early. we have to get inside their planning, we have to get people into their organizations, to essentially report on them. there is a lot that we need to do differently than we've been doing for the last number of years. >> what about in terms of the working with governments overseas, because as we have seen, these are not just immigrants that are recruited by isis, they're people who have grown up in these countries. amri there is talk of refugees, he is not, he made his way to germany. so how do you then work with these foreign governments, and is there enough communication and cooperation at this point in your view? >> no, there is not nearly enough cooperation. our friends in foreign countries, some of them work well with us, like the british, others for example the belgians, i don't know if it's still the case, wouldn't do anything after

5:00 in the afternoon because that was their work schedule. so they wouldn't carry on an attack against terrorists if it was outside the workday. there are a number of things in european organizations that are kind of dysfunctional and they need to work on it, too. as do we. but international cooperation is key to getting inside what is going on in the terrorist groups because different countries that are potentially vulnerable, like us and the british and the french, are going to have different handles on who may be going where in the terrorist groups and where they may be living. these enclaves that the europeans permit to get set up in britain and other places create areas where it's very, very difficult for anybody who is not from a particular part of

the middle east to even go into the neighborhood without getting harassed. it's including police. so our european friends, we have not seen that kind of a problem yet in the united states. but our european friends need to get their acts together and get some control back over the portions of their countries that they have let slide into isis or essentially muslim brotherhood controlled areas. >> we know that one of the major recruitment tools for terror groups, including isis, is the internet in many ways, whether social media, messaging apps and we're hearing from tunisian authorities, the nephew of am ra, telling them he had been communicating with him on this telegram app, encryptions, what

needs to change in terms of staying on top of what is happening online because it doesn't change so quickly? >> great question. it takes a lot of work for us to do that. and we need to turn loose our best code breakers and people who can deal with that out at nsa, at fort mead in washington area. people who work on these issues for the military. we can't really divide things up and say well, we're going to have one group of people work on this, if there is a particular threat at christmastime and otherwise there is this other group. we have to pull this together. and go after the essentially the programs that are instituted to make these apps and so forth very hard to get into. we have to treat this like war.

this is the enemy that is coming at us and we're in a very serious war, it's just that we don't want to admit it yet. >> ambassador wool see, appreciate your time. still to come, the bitter and n antagonistic relationship. how yesterday's vote at the u.n. could be the final straw. ♪ music playing

>> new diplomatic fallout after

the u.s. refuses to veto a controversial u.n. resolution despite pressure from israel and president-elect trump. the resolution condemns of construction of israeli settlements. the vote was 14 in favor with the u.s. abstaining. benjamin netanyahu railed against the resolution saying the obama not only failed to protect israel it colluded with the behind of scenes. israel looks forward to working with president-elect trump and all our friends in congress to negate the harmful effects of this resolution. trump weighing in tweeting as to the u.n., things will be different after january 20th. we're back with former cia director and u.s. ambassador. good to have you back with us. when we look at that tweet from donald trump, things are going to be different after january 20th, is this signaling that it could be the end of the u.n. or somehow u.s. involvement in the u.n. as we've known it?

>> i hope things are different because this is now the second time that president obama has used the united nations and ignored the will of the american people and the american congress in moving out this time against israel. this -- if they will do this, if the obama administration will do this, what are they going to do with the 17 subordinate agreements to the agreement on nuclear weapons that they signed with iran. are they going to show to the congress at all those 17 agreements that have been provided from the iranians to the u.s. government? i don't know what they're going to do with it. they tried the first time to avoid having the constitutional

requirement of a two thirds vote of the u.s. senate for a treaty and they ended up being able to get at least temporarily now, a bypassing of the u.s. senate and an implementation of this agreement even though it did not get the two thirds of approval of the senate that is required in the constitution. the obama administration really likes using the united nations to avoid its responsibilities to the congress and the american people. and i would personally really welcome an end to that, whatever the precise nature of what donald trump and others are thinking about doing. >> we should point out, u.s. ambassador to the u.n. power said basically this is long-standing, our policy has not changed in terms of that. i do want to bring up from lindsey graham said he would introduce a bill to pull u.s.

funding for the u.n. unless the resolution is appealed. writing in a statement that the u.s. has empowered evil and been a poor friend of democracy. as a former director and ambassador, when other countries see this in fighting and see the fact that we have a president-elect speaking out on things while a current president is speaking out on things, how does that play when we see an administration and a country so publicly divided? >> well, you know, division and scrapping is kind of the nature of things for us. madison intended it that way. we've gone since the spring of 1789 every four years having elections and having a stable system and it's stable because we argue with one another all the time and we have checks and balances. i think what is really troubling here is not that we're arguing with one another, but that the

outgoing administration is not doing what it should be doing by way of informing the congress of what is going on and getting congressional approval where the constitution requires it. that's the scandal, not that president-elect trump is making comments. >> we'll have to leave it there. appreciate you joining us. >> good to be with you. >> speaking of land see graham, he will join dana bash to weigh in on the u.n. vote. cnn newsroom continues right after this.

"newsroom." >> this week as president obama attempted to make his final statement as commander in chief, president-elect trump caused a growing rift. the resolution condemning settlements, that passed. before that vote trump demanded obama veto the measure. after the vote trump tweeted to the u.n. things will be different after january 20th. joining me is athena jones, what more are we hearing from the white house? >> reporter: well, the white house is responding to all of this by reminding the public that there is one president at a time. this is just the latest move. trump -- president-elect trump getting involved in this u.n.

vote is the latest move that shows he is not really just preparing for a transition, he is not waiting in the wings, he is making policy pronouncements, whether it is twitter or in interviews, many times they are at odds with the obama administration. you have t u.n. vote, he tweeted about the need for the u.s. to greatly strengthen and expand its nuclear capacity. that seemed to fly in the face of president obama's long standing moves against nuclear proliferation. we heard president-elect trump say that china should keep the drone it took from international waters even after u.s. officials negotiated its return. this is a president-elect who very unusually is throwing himself into the -- these international discussions in a way that past presidents haven't. erika? >> it is not something we've seen before. but a couple of times it has happened. it just put it in context for us. you bring up all the points that

have happened in the last couple weeks with the president-elect talking about things, taking these kind of actions in this case tweeting a lot. but just how unusual is it? >> reporter: it's very unusual. there is a long-standing tradition of incoming presidents, not getting involved in these international issues, not trying to make policy while there is another president in office. they withhold statements or remarks on these important issues. the president's deputy national security adviser put it this way yesterday on a conference call with reporters, he said there is one president at a time. president obama is the president of the united states until january 20th. of course, after january 20th, you have a new president coming in and even president obama himself said look, it's fine to look at foreign policy issues and other issues with a fresh set of eyes, that's exactly what

he would expect of the next leader. it's an obligation he called it. that part is not unusual. what is unusual is the fact that president-elect trump is getting so involved so publicly and so frequently way before january 20th. >> a ththank you. up next, 10%, that is how high foreign imported goods trump could impose once he takes office. in effort to spur manufacturing here in the u.s. will it work? we'll debate it after the break. ♪ ♪ ♪ how else do you think he gets around so fast? take the reins this holiday and get the mercedes-benz you've always wanted during the winter event. now lease the 2017 gla250 for $329 a month

trail on the borders of iraq and syria. two explosions rocking the main terminal at brussels airport. across town in the center of the city, a bomb exploded on a metro train. those three suicide bombers killed 32 people, three months later another airport is hit. three men wearing explosive vets carrying ak 47s, exiting a taxi curb side shooting at panicked travelers before blowing themselves up. 44 people will never make it out of the airport. 6 to 8 gunman have taken over this restaurant in this affluent posh area of the city. military commandos moved in, it ended with 13 hostages saved but 20 others dead at the restaurant. we are following breaking news

>> the trump team is floating an idea to put america first. new tariffs on imports. incoming chief of staff -- tax reform package or could be done by executive order. some critics say it could spark a trade war with other countries. talk it over with our political panel. former communications director for republican congressman. former trump campaign adviser and head of national hispanic advisory council. steve, when we hear that, this is an idea that is being floated, in fact the transition even said they're using this threat of a tariff to get better trade deals, does that mean that we will not see this or is this really on the table?

>> reporter: right. i think you used the correct word which is threat. i think we have to have negotiations, one of the reasons by the way donald trump won is because he has a lifetime of successful negotiations. the people are attracted to that idea that we need a negotiator in chief. i think it is a threat that has to be real, one we won't have to implement. i don't like tariffs, i'm more of a free trade person. a tariff can end up being a tax on consumers, i also think, this is a key reason why donald trump won, the american worker has an unlevel playing field when it comes to trade. there is foreign countries there is no reciprocity and because they're subsidizing their industries for experts here. in a level playing field and the terrorists are a weapon to get to that playing field, the threat of them, the american

worker will perform and thrive, but we need to make it fair for our workers. >> is the threat the best way to negotiate? >> i think we need to be careful about that. that is something that has not worked well for the u.s. economy. the last time we tried this was under herbert hoover and it led to the great depression, one of many reasons and something that even democrats used to saddle republicans with, that protectionist policies were bad for american workers and the economy, for almost 7 years they used that after the disaster of herbert hoover. we need to be careful when we start using tariff threats, because you can in fact spark a trade war that is something we don't want to do. i'm glad to hear steve said he departs from donald trump on the issue of using tariffs, that he is more of a free market guy. as a republican myself i'm actually floored at how many republicans have all of a sudden become protectist republicans and think this is okay.

are there thing that's need to be fixed, are there other solutions that could help spark the economy and help american workers and wages and bring some jobs back, absolutely. but slapping tariffs and threatening that is not the way to do it. president obama tried this with the chinese and the tire industry, some people may remember that, that didn't work out too well. the chinese instead decided to slap a tariff on poultry i am parts that went from 50% to over 100%. so they -- just

politics and social media. boy, the two things that bring us all together, don't they, regardless of party? according to the pew research center, 79% of americans online are using the internet, use at least one social media site. donald trump, of course, is one of them. the president-elect makes the news pretty much wherever he hits that tweet button. just yesterday he suggested the u.s. return to a nuclear arms race, tweeting, quote, the united states must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes.

donald trump's incoming press secretary, expanded on what exactly he meant yesterday when he spoke to cnn. >> he said to her, let it be an arms race. in terms of building up our nuclear capabilities, i guess, against russia. let it be an arms race. because we will out-match them at every path and outlast them all. what does "let it be an arms race" mean? >> i think he is going to do what it takes to protect this country. and if another country or countries whatnot to threaten our safety or or sovereignty, he's going to do what it takes. >> sure, but -- >> so every tweet, you are telling us, from now on with u.s. press secretary, that we are to be able to take those words literally? >> of course, you can. if they're from him, they're -- i mean, i don't know what else you would take them as. >> our next guest is an expert in using social media effect live. jim anderson is the president of so ho flow.

so i know you actually have some data on that nuclear arms tweet from donald trump. give us a snapshot of the impact that one tweet had. >> yeah, erica, it's amazing. donald trump has 18 million follow hearse on twitter, and that tweet was one very notable one. he tweets 125 to 150 times a month on average. the real impact, though, comes from the media coverage of what he says. and let's not forget that that's one of the important parts of his candidatcy. and i think will be one of the important parts of his presidency, he says something provocative on twitter. yes, a lot of people hear about it, but the amount of media coverage that comes in and provides the amplification to that message is huge. 300 times, at least, by comparison, just on twitter alone. >> it's huge, but oftentimes it ends up with a little bit of a back and forth. and there's a need for clarification. and yet we just heard from his incoming press secretary, sean spicer, he was talking with our alisyn camerota yesterday and say, yes, you should absolutely take every tweet, as long as it comes from donald trump, literally. and yet we've had to see him go

back on things or clarify things. so, even though he's using it, and yes, it's getting covered, because he's making news on them, is he using twitter effectively? >> well, yes, in that he's getting a tremendous amount of attention, but i think this is where we see a shift from donald trump the candidate to donald trump to president-elect, to donald trump, the president. and i think one of the really important roles of the media is going to be to try to understand and provide context. i don't believe, for a second, that everything donald trump says by twitter will be taken literally or should be taken literally. and you see that with his advisers. some of them are trying to walk back what he said. some are trying to reinforce or shift that. and i think that's one of the real questions of his presidency, once he's sworn in, is how does that actually play out and how does the media go to the various advisers and cabinet members skpuand understand what really meant on twitter. >> so what's your advice to him, as he shifted from candidate and now president-elect and will then shift to president, and by

all accounts, will continue tweeting, what's your advice on leveraging that in the most effective way possible, not just for himself, but for the country. >> i think the key advice is recognize the difference between being a candidate and being president, president-elect right now, soon to be president. we've seen his tweets can move the markets. boeing, lockheed, those kind of stock movements are great indicators of the power of the presidency. and that's just the economic power, never mind the military power. so i think one of the key conversations he's going to have to have with his administration is how do we sort of remain true to ourselves and what got us here, and then how do we moderate that? we all know that governing is a lot different than running for presidency. so you'll see some dampening. i don't know that his personality is well-suited to being dampened or controlled. but i have to believe it's inevitable that you'll see some dampening of what he says on twitter. >> jim, real quickly, how has donald trump's use of twitter changed the perception of this as a social media tool? >> well, it certainly has made it incredibly relevant. you know, twitter has always

been at its best when it's live and raw and authentic and unfiltered. and that's initial. >> it's a perfect match and the fact that we're talking about twitter so much, in this context not so much about facebook or snapchat is important in terms of highlighting how twitter with be used for good and bad, it certainly is relevant and i think will remain so. >> jim apdnderson thank you for joining us. many of us take for granted, a send a passage and it gets to the destination, that is no easy task. an inside look at how fedex gets it done.
