Reporter: This morning, as billionaire Michael Bloomberg tries to sell his vision of the future to voters, president trump is laser focused on bringing up Bloomberg's past as mayor of New York. Now, the president attacked me this morning on Twitter. And he attacked me again this afternoon in an interview. So let me say this, Mr. President, you can't bully me and I won't let you bully the American people. Reporter: This comes as Bloomberg faces fresh scrutiny over the controversial stop and frisk policing program he expanded in New York City. The president blasting Bloomberg making this exaggerated claim in a radio intersue. Bloomberg came in and he said, well, you know what, this thing is so good, I'm going to stop every black person, and if you were a black person in new York, you were stopped two times a day, three times a day. You couldn't go to your house, they were stopping you every day. Reporter: But president trump praised and promoted the policy in the past. Stop and frisk had a tremendous impact on the safety of New York City, tremendous beyond belief. Reporter: He isn't the only candidate they're hounding. Rush Limbaugh launching this homophobic attack against Pete buttigieg. A gay guy 37 years old, loves kissing his husband on debate stages. Can you see trump have fun with Reporter: President trump insisting he has no problem with buttigieg's sexuality but saying some voters might. I think so. I think there would be some that wouldn't and, you know, I wouldn't be among that group to be honest with you, but I think that, yes, I think that it doesn't seem to be hurting Pete buttigieg. There would be a group that probably wouldn't, but, you know, you and I would not be in that group. Reporter: Coming to the former South Bend mayor's defense former vice president Joe Biden. Pete and I are competitors. This guy has honor. He has courage. He's smart as hell. Reporter: Appearing with his wife Jill on "The view" Biden expressed confidence that even though getting what he described as gut punched in early primaries, he is still the best candidate to take on the president. I believe I'm going to beat trump. Reporter: Behind the scenes his campaign trying to reset. By redeploying resource, moving money and staffers. Some from super Tuesday states into Nevada and South Carolina. Biden desperate for strong finishes in these next two contests where for the first time in this election cycle minority voters will play a major role. You know, 90%, 99% of the African-American vote hasn't voted yet and 99% of the humanitarian vote hasn't voted yet.
