Ex-conservative GOP Rep. Justin Amash, I-Mich., on Thursday lashed out at Republicans for "excusing" President Donald Trump's "misbehavior" ahead of a vote in favor of a House impeachment resolution.
"This president will be in power for only a short time, but excusing his misbehavior will forever tarnish your name," the Trump critic tweeted.
"To my Republican colleagues: Step outside your media and social bubble. History will not look kindly on disingenuous, frivolous, and false defenses of this man."
Amash joined 231 Democrats supporting the resolution that establishes rules for open hearings and the questioning of witnesses by House committee members and staff, The Hill pointed out.
"Don't let President Trump or Republican officials distract you with a straw man," Amash tweeted in September after Democrats launched the inquiry. "It's about his continuing abuse of the office of the presidency."
Amash first lent his support to an impeachment inquiry after the release of former special counsel Robert Mueller's report on Russian interference and possible obstruction of justice by the president, The Hill reported, saying Mueller's probe identified "multiple examples of conduct satisfying all the elements of obstruction of justice."
"There are lots of Republicans out there who are saying these things privately, but there not saying it publicly, and I think that's a problem for our country," he told CNN at the time.
Amash left the GOP in July.
