MORE touted his election victories on Tuesday night amid the growing presence of an anti-Trump movement and called for Republicans to unify.

"This was an amazing evening. I don’t think I’ve ever had so many horrible things said about me in one week," Trump said at press conference in Jupiter, Fla., a week before the state's primary. "It shows you how brilliant the public is because they knew they were lies.

"The bottom line is we have something going that's so good," the GOP presidential front-runner said. "We should grab each other and we should unify the party."

On Tuesday, Trump won primaries in Mississippi and Michigan as he continues to extend his delegate lead. Republicans also went to the polls in Idaho and Hawaii, where voters are still casting ballots.

Trump dedicated a good portion of his victory speech to listing his business ventures in a several minutes long rebuke to Mitt Romney, who had painted Trump as a fraud with failed businesses.

The real estate mogul stood on stage at his Florida headquarters surrounded by props he said refuted the 2012 Republican nominee's claims that he had left behind him a string of failed companies.

"Mitt got up, and he really shouldn't have done it. It wasn't becoming, honestly," Trump said of Romney's speech last week.

"He talked about the water company," Trump said. "Well there's the water company, I mean we sell water and we have water and it's a very successful, you know, it's a private little water company and I supply the water for all my places, and it's good, but it's very good."

Trump then pointed to what he said were Trump steaks, Trump magazine and Trump wine.

He also highlighted the record voter turnout among Republicans and noticeably shifted his tone at one point, as he called for unity among the party.

Trump called for voters to protect GOP incumbents up for reelection this cycle. Democrats and Republicans are in a heated battle for control over the Senate.

"I must tell you it's very, very important that our senators and congressman get reelected," Trump said, adding "if we're going to be effective, it's very, very important."
