this morning on "world news now," immigration overhaul. the many new actions taken by president trump that leave millions hanging in the balance from building a border wall to the children of undocumented immigrants. our david muir questioning trump on it all. >> also from that interview, the president explains his unsubstantiated claim that millions of fraudulent votes costed him the election. hear why he is now doubling down, calling for an investigation. also this half hour, the passing of an entertainment legend. >> the woman behind the infamous hat toss that inspired a generation of women to chart their own course. we're looking back on the life and ground breaking career of mary tyler moore. and what recording legend stevie wonder did lately that has one young musician saying isn't he lovely. and he's completely overjoyed right now.

and reaching higher ground. i think that was four stevie wonder puns in all of that 20-second video there. it's thursday, january 26th. from abc news, this is "world news now." the only ones i couldn't reach, ebony and ivory in there somehow. i was trying to figure it out. we'll get to that story a little bit later on. we'll start this half hour with the uproar over president donald trump's sweeping crack down on illegal immigration, including the executive order to jump start construction of his promised border wall. >> the mexican president enrique pena nieto announced last night mexico will not pay for any wall, but president trump insists the u.s. will save lives on both sides of the border and he brushed off mexico's continued resistance in an exclusive interview with abc's david muir. >> david, i think he has to say that. he has to say that. but i'm just telling you there

it will be in a form, perhaps a complicated form and you have to understand what i'm doing is good for the united states. it's also going to be good for mexico. we want to have a very stable, very solid mexico. >> when does construction begin? >> as soon as we can. as soon as we can physically do it. >> within months? >> i would say in months, yeah, i would say in in months. certainly planning is starting immediately. >> nieto is scheduled to meet with president trump at the white house next week but sources say he's now considering calling off that trip. in addition to building the wall, the president took action to remove some of the 11 million undocumented immigrants living here now. abc's cecilia vega has details. >> reporter: president trump at the department of homeland security signing those executive orders on immigration. >> we've been talking about this right from the beginning. >> reporter: the move coming after that signature campaign promise. >> build that wall! build that wall! >> reporter: in addition to building that wall, the president also vowing to strip federal funding from so-called sanctuary cities that

shield undocumented immigrants, triple the number of i.c.e. agents and add thousands more border patrol agents. >> beginning today, the united states of america gets back control of its borders, gets back its borders. >> reporter: no specifics on how to pay for that wall. but president trump putting on notice millions of undocumented immigrants, including those who have been charged with a crime, even if they have not been convicted. >> we're going to get the bad ones out, the criminals and the drug deals and gangs and gang members and cartel leaders. the day is over when they can stay in our country and wreak havoc. >> reporter: protests in new york and by the white house. and sanctuary cities firing back. >> this city will not be bullied by this administration into abandoning our core values. and we believe we have the rule of law and the courts on our side.

>> cecilia vega, abc news, washington. despite the president's tough stance on immigration, one group may be allowed to remain in the country. >> the so-called dreamers, those brought here legally as children, may escape deportation. they're now protected under president obama's policy. while president trump isn't making any promises about their fate, he told david there is no need for concern. >> they shouldn't be very worried. they are here illegally. they shouldn't be very worried. i do have a big heart. we're going to take care of everybody. we're going to have a very strong border, we're going to have a very solid border where you have great people here that are here that have done a good job, they should be far less worried. we'll be coming out with policy on that over four weeks. >> reporter: will they be allowed to stay? >> i'll tell you over the next four weeks. we're looking at this. the whole immigration situation. we're looking at it with great heart. now, we have criminals that are re. there are a number of protests in response to this is, too.

where he is saying he wants to restrict certain refugees coming in and, you know, it's just one of those issues that got a lot of people talking. > in particular with the dreamers saying it might be a little bit of a difficult thing for him. he actually got 29% of the latino vote. so 2% more than mitt romney did. a lot of people said it's a controversial one, something that you promised that there would be some changes about, but it may end up hurting a big voting bloc for you, surprisingly big voting bloc for him. >> we're hearing him say i have a big heart. they don't have to be worried. there's still a lot of blurry lines how this law will be enforced and what he's do going forward. the president in the meantime is standing by his claim rampant voter fraud in november's election and he says he's launching an investigation. >> so the president is insisting that millions of dead people, illegals as he says and people registered in more than one state, cast votes. none of those, he says, for him.

and despite that, he said he still could have won the popular vote if he had just changed his campaign strategy. >> i would have won the popular vote if i was campaigning for the popular vote. i would have gone california where i didn't go at all. i would have gone to new york where i didn't campaign at all. i would have gone to a couple places that i didn't go to and i would have won that much easier than winning the electoral college. as you know, the electoral college is all that matters. >> valid point. >> yes. >> but that said, hillary clinton also didn't necessarily campaign in california except to go fund raise near los angeles and san francisco most of the time you but she beat him in california. >> they went back and forth over this pew report because trump is claiming there's a lot of voter fraud and that's why. and so it gets a little bit confusing but just to give a little background, they're referring to a report in 2012 which found irregularities in voter registration so that people who were deceased or region

two different states. there was no actual voter fraud. they didn't vote or vote twice. they're voter registration that the pew report blamed on an antiquated system. >> his chief strategist who was registered in florida, and in california and his daughter registered in both places. >> it happens a lot when people move. so clearly a problem there. but pew is saying no actual fraud. one last bit from the interview, the president campaigned on a pledge to repeal obamacare. he told david when it comes to health insurance, he wants to "take care of everybody." >> yeah, the president said he wants to make sure nobody's dying on the streets when he's president. he seemed to give republican lawmakers a green light for action. >> it's too expensive. it's horrible health care. it doesn't cover what you have to cover. it's a disaster. you know it. and i know it. i said to the republican folks, and they're terrific folks, mitch and paul ryan, i said, look, if you go fast and i'm okay

the right thing to do, we want to get good coverage at much less cost. i said if you go fast, we then own obamacare. they're going to put it on us. obamacare is a disaster waiting to explode. if you sit back and let lit explode, it's going to be much easier. that's the thing to do, but the right thing to do is to get something done now. >> we'll see how soon they act. >> they might move quickly. on the other hand, they might wait? >> many of the experts say it would be impossible for them to move quickly. if anything is done, it will take the next four years. >> though trump says obama is rooting for him and the president said if your health care plan turns out to be better than mine, then i'll support it. >> yes, probably rooting for him in that mystery letter that we didn't get to see from the president. >> >> what's in the box and what's in the envelope. we want to know. >> what is it in the tiffany box. so a very common sight at trump campaign events was tom llamas. now some congrats i guess you could say to t g

>> a sleazy guy with emphasis he said it. an annual list says that tom was actually the most used reporter of 2016 on three evening network newscasts, he logged 482 minutes of air. >> amazing. > that is more than 100 minutes over the reporter who came in second. >> and just for the record, that means that his kids, his two kids have seen him more on tv nage they saw him in all of 2016. >> at times relieved the campaign is over. >> i think so. coming up, remembering a television legend and that iconic hat toss. >> yes. >> mary tyler moore became so famous for, twirling her hearts into just generations of fans. we will show you how co-stars are remembering their friend. >> and speaking of women on television, how steph curry's little girl, riley, managed once again to steal the show. that's in "the skinny." first here's a look at today's forecast.
