President Donald Trump called a GOP lawmaker a "moron" at the National Prayer Breakfast on Thursday.

Trump was talking about Republican U.S. Rep. Thomas Massie of Kentucky, who sometimes votes against the party.
Early in his remarks Thursday, Trump turned to the topic of legislation and said Republicans will typically rally together after some finagling — all of them, he said, except for Massie.
"No matter what we do, this moron, no matter what it is," Trump said.
"We'll get a 100% vote except for this guy named Thomas Massie. There's something wrong with him."
Massie, a libertarian-leaning representative, has drawn the president's ire for saying he lacked the authority to attack Iran's nuclear sites without congressional approval, voting against Trump's massive tax and spending cuts bill and fighting for the release of the Jeffrey Epstein files.
