Democratic Sen. Chris Murphy told reporters that he was emotional in the chamber as he listened to Republican Sen. Mitt Romney say he will vote to convict President Trump.

Murphy’s voice was shaking as he told reporters, “I was choked up listening to him speak.”

He said it was the “toughest thing in the world” to stand up to his party and donors.

Murphy said that history would remember Romney kindly.

Hawaii Sen. Brian Schatz took to Twitter to champion Romney.

"Thank you, Mitt. You have restored my faith in the Senate and the idea that putting country over party is still possible," the Democratic senator said.

Just moments ago: Romney, a Republican from Utah, said what Trump did “was a flagrant assault on our electoral rights, our national security, and our fundamental values."

"Corrupting an election to keep oneself in office is perhaps the most abusive and destructive violation of one's oath of office that I can imagine," he added.
