>> announcer: from abc news, this is "world news now." good morning, everyone. >> i didn't mean to yawn on camera. i'm obviously hugely excited by the content of the show. i'm not used to this night shift. >> you said you only got three hours' sleep. yesterday you were so pumped up ahead of the show by the donald trump comments. your fellow countrymen, your prime minister weighed in, and even j.k. rowling, weighed in. >> and also boris johnson, mayor of london, made some quite funny comments about it. >> really? >> we're going to read some later. i do like the implication from you that they followed me. i made comments last night -- >> they followed you on twitter, saw the broadcast across the pond and -- >> well, i am not going to

disagree with that. but we begin with donald trump. with his republican rivals showing no mercy in his ban on muslims. donald trump is not ruling out leaving the gop and running as an independent. >> it could cost republicans the presidential elections. a new development this morning, trump is planning a trip to israel at the end of the month. >> all that as the controversy over trump's plan to ban muslims shows no signs of slowing. it's your voice, your vote and our coverage begins with tom. >> donald trump is calling for a total and complete shutdown of muslims entering the united states until our country's representatives can figure out what the hell is going on.

>> reporter: trump justifying the ban by painting apocalyptic future if we don't ban them. >> we'll have more world trade centers. we can be politically correct and stupid, but it's going to get worse and worse wrt with even his own party condemning, trump is invoking roosevelt actions against germans, italians and japanese in america during world war ii. cover of the philadelphia daily news compares trump to a different figure. >> the new fire over donald trump. you're increasingly being compared to hitler. does that give you any pause at all? >> no. because what i'm doing is no different than what fdr -- fdr's solution for germans, italians, japanese, you know, many years -- >> you're for internment camps? >> this is a president who is highly respected by all. he did the sale thing. >> reporter: trump insists he's

not calling for internment camps but he is calling for new scrutiny of mosques. >> yes, we have to look at mosques. we have no choice. we have to see what's happening because something is happening in there. man, there's anger. there's anger. >> reporter: and from south carolina -- >> i like the ban on the muslims. we just have to get control. >> reporter: trump seems to have no control doing business with muslims, but he's now encouraging profiling, urging his supporters to sound the alarm. america hasn't heard ideas like this or language like this from a presidential candidate in generations. the question, the big question, does this stop trump cold or make him more popular? tom yam, abc news. >> does it make him more popular? >> you couldn't stop watching that interview. george, i don't know if i would handle it as well as he did. >> he picked him up very well. >> we'll hear more of trump's critics in a moment.

at one point he said bluntly, quote, i don't care about them. >> abc's barbara walters, no less, sat down with trump yesterday for his only on-camera interview since his controversial comments. >> do you regret your ban on muslims, which some people think is un-american? >> not at all. we have to do the right thing. somebody in this country has to say what's right. i have great respect and love. i have people that i have tremendous relationships with. they're muslim. and, barbara, they agree with me 100%. it's short term. let our country get its act together. they knocked down the world trade center. they tried doing it twice. other things have happened. there are a lot of -- there are people that have tremendously bad intentions. we have to be tough, smart and vigilant. >> reporter: what is short term? >> it could be very quickly if our country could get its act together. we don't know what's happening. we have a president that doesn't

have a clue. we don't know what's happening. we need toughness and smartness and we have to do it quickly. >> there are many, even in your own party, who think that isis is going to like your rhetoric. that your words are putting us in greater danger. >> and the worst thing that's ever happened to isis. the people in my party fully understand that. they're running against me. for the most part, they have no poll numbers. i'm leading by a like. they get it. they're trying to get publicity for themselves. when i came out against illegal immigration, everybody for the same thing, two weeks later everybody was on my side, including members of my own party. >> are you a bigot? >> not at all. probably the least of anybody you've ever met. >> because? >> because i'm not. i'm a person that has common sense. i'm a smart person. i know how to run things. i know how to make america great again. this is about making america great again. >> donald trump there speaking

and the mayor of london says, this isn't true. and then he says, the only fear i have of walking the streets is that i might run into donald trump. >> did he really? >> i thought barbara's interview was fantastic. he commented, i'm the least bigoted person you have ever met. i don't know whether it's true or not, but yet another staggering comment that falls from his mouth. >> and so many americans support him and trust him and believe he's the future. >> and so many that watch this program, we asked yesterday on twitter, these comments, do niece make you more devout or off-putting him. >> we are hearing for the first time from some of the first responders who arrived on the horrific scene of the san bernardino shooting. among them, a 15-year police veteran that reassured evacuees by saying, i'll take a bullet for you. here's abc's lauren lister. >> reporter: first responders remembering the victims of last week's tragedy. >> never, ever thought i would deal with anything like that.
