And take questions from reporters. He may sign some executive orders and may also meet with his new defense secretary, james mattis, and lay out his objectives in fighting isis. He spoke a little bit about the challenges when fighting this enemy. Take a listen. The people were going against dont wear uniforms. Theyre sneaky, dirty rats. And they blow people up in a shopping center. And they blow people up in a church. These are bad people. When youre fighting german and they had their uniforms and they had had their uniforms and japan and they had their uniforms and their flags on the planes and the whole thing, we are fighting sneaky rats that are sick and demented, and were going to win. Reporter donald trump is also expected to have a very busy weekend ahead. Hes going to be speaking with a number of world leaders, leaders in france, in germany, but also russian president Vladimir Putin. Obviously this is someone who has not had a great relationship with u. S. Leaders in the past. And it comes at a time that were seeing a sort of rocky diplomatic debut from donald trump, tensions between the u. S. And mexico are flaring, and the president of mexico just said he is no longer going to come to the u. S. For a meeting with President Trump next week, carol. Sara murray, thanks so much. All of this as President Trump, as you heard sara say, adds fuel to the rift with mexico. President trump tweeted that mexico has been taking advantage of the u. S. Long enough, as he floats the idea of floating a 20 tariff or tax on imports to pay for his wall. Cnns leyla santiago is live in mexico city with reaction. Hi, leyla. Reporter carol, were talking about a big meeting at the white house. Well also be seeing a pretty big meeting here at los pinos, the equivalent of the white house, where the president has a mansion. Hes going to have the mexico president , hes going to be meeting today with the delegation that was in washington, dc this week, reporting back on what they learned, what came out of those meetings with trumps staff this week. So we expect to get quite a bit of reaction, not only from the president , but also some of the senators, the Business Leaders in mexico on exactly how they move forward with this new relationship today. Also today, quite a big player here, were expecting for carlos slim to speak, one of the richest men in the world, a multibillionaire. He had a bit of a back and fos h forth with President Trump during the campaign. He is expected to speak out today, somebody who typically doesnt speak publicly on a lot of diplomatic things. It will be interesting to hear what he has to say. Also speaking out, the foreign minister. Here is what he said. We simply cannot accept the concept of a neighbor paying for your wall. This is something we will never do, because this is about this is about our dignity and our pride. Reporter so clearly strong stakes, people applauding president Enrique Pena Nieto for not being bullied. I thought it was interesting, when we were at the newspaper stand this morning, the vendor looked over and said, hes picking a fight with everyone. So were certainly seeing this as quite the talker. But it seems that here in mexico city, there is a sense of pride, as if dignity has been restored in this cancellation of the meeting and how they will move forward in this new relationship, carol. All right, leyla santiago, live from mexico city, thank you. Lawmakers on both sides of the aisle in the United States are not lying this tariff idea. Cnns manu raju is live in philadelphia with that. Hi, manu. Reporter hi, carol. The idea of how exactly to pay for the wall is something that is dividing both parties on capitol hill. The question is, now that mexico is saying they will not pay for the wall, will u. S. Taxpayers now be stuck for paying for it . Democratic senators are telling me, and sources, that they believe whatever funding package the Trump Administration sends to capitol hill will not get 60 votes in the United States senate, meaning it will be very unlikely that congress will approve a funding package because of opposition from democrats, including conservative democrats, over how this would be funded. Either through a 20 tax that the white house suggested was an option yesterday, or simply by adding upwards of 15 billion to the deficit. Now, just moments ago, Senate Minority leader chuck schumer, the new york democrat, issuing this statement the cost of everything from groceries to cars to Office Supplies would go up 20 , making it hard for middle class families to pay for things they need everyday, Lindsey Graham tweeting hes, quote, mucho sad about the idea that the cost of marguerite thats and coronas could increase by 20 . But republicans who support this idea say thats a misguided notion, that its all part of a larger effort to reduce corporate taxes. Suffice to say, opposition and concern about the approach that the Trump Administration is taking to get congress to foot the bill initially. And major questions about whether they could even get the package out of congress, because Senate Democrats could block it in the United States senate, just in a matter of months, carol. Manu raju, reporting live from philadelphia. If President Trumps relations with mexico could be subscribed as frosty, consider the warm and glowing praise from british Prime Minister theresa may. She visited the republican retreat in philadelphia. Rooted not in the corridors of washington but in the hopes and aspirations of working men and women across this land. Because of that great victory you have won, america can be stronger, greater, and more confident in the years ahead. Cnn International Diplomatic editor Nic Robertson joins me from washington. Will it be a friendly meeting between the two leaders this morning, nic . Reporter that speech by theresa may yesterday may look like it leapt off the pages of how to make friends and influence people. Shes saying britain wants to align itself with the United States. This long history of helping win wars together, the shared sacrifices together. Her visit to Arlington National cemetery earlier today speaks to that, that britain and the United States have lost many lives in sort of building the world in their own model, in their own way, if you will. What she wants to do and what shes saying now is that the future is a shared vision too, that britain is turning away from this international or liberal interventionism. This is how she put it. The days of britain and america intervening in sovereign countries in an attempt to remake the world in our own image are over. But nor can we afford to stand idly by when the threat is real and when it is in our own interests to intervene. Reporter so that influence people part of the list, weve seen the making friends, she would like the United States to remain a strong supporter of nato, to have a stronger view of the importance of unity in europe and be a little more cautious about the relationship with russia and president putin. Yes, she wants to try and influence President Trump. How strongly will she go in that language behind the closed doors of the oval office, not clear. Nic robertson reporting for us, thanks so much. With me now is david gergen, former president ial adviser to ford, nixon, reagan and clinton. Rebecca berg for real clear politics, and david rowe from reuters. David, you have a strong american i lie saying the president of the United States is, you know, trying to take away its dignity and its pride. You have theresa may reaching out and apparently maybe a warm conversation. And you have this phone call with Vladimir Putin that we assume will be friendly because mr. Trump has been so supportive of Vladimir Putin in the past. So put this into perspective for us. Well, donald trump is off to a whirlwind start, isnt he . Hes going through executive orders and phone calls and one thing and another. What Franklin Roosevelt did in his first hundred days, that is a tremendous number of changes, hard to put it all into one package, you know, if youre on the outside. But theres no question that in his relationship with mexico, he sent a message to one of our closest friends and our Third Largest trading partner after canada and china, that he was going to force changes. They see this as bullying. I think that sent a message not only through mexico but through much of latin america that there may be a very difficult period in the relationship with the United States. On the other hand, theresa may has got a very, very different agenda. Shes come in just after brexit or the separation out from the uk from the european union, and shes the one who is executing that. And shes trying to approve to britain, to europe, and to the world that brexit is not going to lead to a british disaster. It is in fact going to allow her to strengthen the relationship with the United States. She wants more access to markets here, she wants to have a trading relationship. She sees that as being part of a global power. From Donald Trumps point of view, he is going to welcome her because he wants to prove that brexit worked, and theres a great fear in the continent of europe, president hollande of france has been meeting with chancellor merkel of germany, that the combination of may and trump may help to unravel the european union, may help to bring these other populist movements to power on the continent. And its causing real heartburn in france and germany. David, when mr. Trump was running for office, he was this great deal maker, right, he was adept as negotiation. Is he showing that right now, david . Well, you can find two sides on that, almost every issue with donald trump. His supporters think hes doing exactly the right thing, its time to stand up to mexico and all the rest. The traditional, more conventional view, and one that you would find in the state department, for example, going back decades, is that yes, we have our differences, but they ought to be settled quietly around the negotiating table because we are friends. I was with president clinton during the nafta fight when nafta was being negotiated, the ending part of nafta, and then getting it past. I can tell you, every day there were tons of phone calls between the u. S. And the mexican sides trying to see if we could hammer out an agreement on Little Details that would mean a difference on votes. And it worked out very successfully. I mean, you can argue about whether nafta has been good for American Workers or not, thats a controversial question. But theres no question that the negotiation itself was an amicable one that really i think strengthened ties between not only the United States and mexico but across north america. We began to move to a single free market here in north america, a vision that Ronald Reagan and many others have had over the years. David rowe, all of this matters when it comes to National Security too. You heard what mr. Trump said about isis, this is a different kind of enemy, which i think all americans understand. So how does that fit into whats happening now . Well, to be frank, theres a disconnect. There has been no single terrorist attack carried out in the United States that involved anyone crossing from mexico. Immigration has been flat, if you look at it over the last few decades. Thats whats unclear. This call with putin this weekend is crucial. At the same time theyre going to ban visas to all seven predominantly muslim countries. To win over isis we dont need russia, we need arabs and muslims. Afghans, syrians, we need those allies on the ground. So this talk of a ban on immigration from these seven prominently muslim countries will help isis recruitment. It plays into a narrative that the United States is biased against islam. So the American People are sitting back and watching. Rebecca, a new quinnipiac poll says mr. Trump has a 36 approval rating. What does that say about his actions to date . Well, carol, it says quite simply that he has a lot of work to do. And part of this, he can use this discussion with foreign leaders to begin to reassure a lot of americans who feel that he has been a little bit triggerhappy in his first few days at president , but also during the transition, and who worry about his temperament as president , who arent sure how he will act in these situations, either with foreign leaders or dealing with congress or signing executive orders. And so really his discussions with theresa may, his discussions by phone with Vladimir Putin upcoming, these can be some real opportunities for donald trump to show that he is going to be a serious player on the world stage, to show that he will be a good steward of the United StatesForeign Policy abroad. But its also a very risky situation for him, because it can go in completely the opposite direction. We know that donald trump operates in a way that the foreign leaders, that diplomatic communities, not necessarily familiar with. Its very different from what theyre used to. And so its a risk as well as an opportunity. But he does have a lot of work to do. And, you know, i would point, carol, to his inaugural address. Donald trump had an opportunity to reach out to americans who are still skeptical of him, to pledge to unite the country, and he didnt. His message played directly to his base. It was really just a Campaign Speech rejiggered for the inauguration. And so he still does need to take that opportunity at some point, i would argue, to speak to those americans who are still very skeptical of him. I have to leave it there. Thank you so much. Is he disciplined, is he keeping his promises, or is he preoccupied with being popular . A special, trumps first week in office, tonight on 9 00 p. M. Eastern on cnn.

President trump tweeted that the miamidade mayor made the right decision. Ill get the mayor on the phone in just a minute. First i want to back up and talking about exactly how we got here. There are about 300 cities and towns who have policies protecting undocumented immigrants from deportation. On wednesday, President Trump signed an executive order that aims to strip away federal money from those sanctuary cities and counties. Some mayors, though, are holding the line. I want to be clear. Were going to stay a sanctuary city. If necessary well use city hall itself to shelter and protect anyone who is targeted unjustly. Im talking to all mayors in this country. Are the mayors going to unite to draw a line in the sand . We have. We want the federal government to protect those folks who have gotten temporary legal status and we want the overall system to be fixed. And as i told you, the miamidade mayor is instructing his county jails to crack down. Mayor Carlos Gimenez joins me now by phone, good morning, sir. Good morning, how are you . Im good. Is this a complete break with the other mayors who govern sanctuary cities . Absolutely not, because we never considered ourselves to be a sanctuary city. Simply the directive that i gave is that the county commission had, in 2014, put out a resolution that stated that if we did not get verification of reimbursement for those inmates that we had currently under our jurisdiction that the federal government requested, that we would let them go whenever their time was served, whenever they had to go. Before that time, we would honor the request of the federal government to detain inmates that they wanted without regard to the compensation to the county. Because it had cost us about half a Million Dollars over a number of years in costs that had not been reimbursed by the federal government. All i did yesterday was say that we dont need the documentation saying that they will reimburse us for the cost in order for us to honor the request to detain somebody who has been arrested in Miamidade County. In other words, and im just going to try to shorten this because its a very complicated issue, when Police Arrest an undocumented immigrant, and that person goes to jail and is accused of
