Mitt Romney took his shots at Donald Trump Thursday morning, and Trump returned fire Thursday afternoon. His verdict: Romney is "irrelevant" after running "one of the worst campaigns in the history of politics." At one point, Trump took a shot at Romney as two-faced because he said Romney was "begging" for his endorsement four years ago. "I could have said, 'Mitt drop to your knees.' He would have dropped to his knees," Trump said during a campaign stop in Maine, reports the Hill. He also said Romney "chickened out" of this year's race only because he feared running against Trump. "He's a choke artist."
He called Romney's assault against him "very nasty," adding, "I thought he was a better person than that." Trump, who had to pause four times during his speech as police escorted protesters from the room, dismissed Romney's criticism of his business savvy. "Nobody knows more about free trade than me," he said. "I made so much more money than Mitt." And as for Romney as a presidential candidate: "He let us down. He let us down," Trump said, per Politico. "He was horrible in the third debate. Something happened." (Read more Donald Trump 2016 stories.)
