A growing number of Republicans want President Donald Trump to leave office before January 20, with some top lawmakers telling CNN they are considering supporting his impeachment.

Two Republican members of Congress who are former Trump allies told CNN they would support impeachment against the President over his role in Wednesday’s deadly attack on the US Capitol if the articles are reasonable. One member said, “I think you will have GOP members vote for impeachment.”

While the window is narrowing for an impeachment vote and trial before Trump’s term ends, one of the GOP lawmakers said the proceedings could be done quickly.

“We experienced the attack,” the member said. “We don’t need long hearings on what happened.”
