A Michigan lawmaker became the first Republican congressman to acknowledge the possibility that allegations President Donald Trump may have asked fired FBI Director James Comey to drop a probe into his campaign could lead to his impeachment.

Asked on Wednesday if the allegations, if true, would merit impeachment, Rep. Justin Amash said "yes."

"But everybody gets a fair trial in this country," he added, leaving the House GOP's conference-wide meeting Wednesday morning.

Trump has come under fire following a bombshell report by The New York Times on Tuesday that Comey had kept detailed notes of his meetings with Trump, including one the day after now-former national security adviser Michael Flynn was fired for misleading Vice President Mike Pence about his conversations with the Russian ambassador to the U.S.

In that February meeting, according to the Times report and later verified by multiple news organizations, Comey's notes say Trump asked the FBI director if he "can let this go," referring to the burgeoning investigating into Flynn's alleged ties to Russia, including accepting tens of thousands of dollars in payments from several Russian companies.

The meeting in question took place without anyone else present – Comey says Trump asked Pence and Attorney General Jeff Sessions to leave the room before suggesting Comey drop the Flynn probe. And unless Trump did record his conversations with Comey – as he hinted in a tweet last week he might have – the truth of what exactly was said may come down to Trump's word versus Comey's.

Amash told reporters he would take Comey's word over Trump's, if it came down to that.

"I think it's pretty clear I have more confidence in Director Comey," he said.

While some Democrats have been agitating for impeachment for some weeks – Rep. Al Green of Texas took to the House floor on Wednesday to call for Trump to be brought up on charges of obstruction of justice – most Republicans have been reluctant to criticize the president.

But Amash – who along with Rep. Walter Jones of North Carolina are so far the only Republicans to back a Democrat-sponsored bill to form an independent commission to investigate possible collusion between Trump's presidential campaign and Russia – has frequently clashed with Trump.
