President Donald Trump issued an enthusiastic endorsement of Mitt Romney’s 2018 Senate bid. “He will make a great Senator and worthy successor to @OrrinHatch, and has my full support and endorsement!” the president tweeted Monday evening, following the 2012 Republican presidential nominee’s official announcement last week that he will be running for Hatch’s seat in Utah. In early 2016, Romney labeled Trump a “phony” who was “playing the American public for suckers” and “has neither the temperament nor the judgment to be president”; Trump fired back, calling Romney a “choke artist” who was “begging” for his endorsement during the 2012 cycle. Romney was more deferential toward Trump after the 2016 election and was reportedly considered for the secretary of state position before Rex Tillerson was picked. In response to Trump, Romney thanked the president for his endorsement despite tweeting in 2016, “If Trump had said 4 years ago the things he says today about the KKK, Muslims, Mexicans, disabled, I would NOT have accepted his endorsement.”
