Donald Trump responded to Mitt Romney’s speech Thursday during a rally in Maine, hitting the former Republican nominee by saying he would have gotten on his knees for the Trump endorsement back in 2012. “I am not a fan of Barack Obama and that was a race that I backed Mitt Romney, I backed him, you can see how loyal he is,” Trump said. “He was begging for my endorsement. I could have said, Mitt, drop to your knees, he would have dropped to his knees, he was begging. He was begging me.” At another point, he railed against Romney as a “choke artist” and said “chickened out” of running again in 2016.
