Iowa Sen. Joni Ernst said Republicans may not waste any time trying to impeach Joe Biden if he wins the White House.

“I think this door of impeachable whatever has been opened,” Ernst told Bloomberg News on Sunday. “Joe Biden should be very careful what he’s asking for because, you know, we can have a situation where if it should ever be President Biden, that immediately, people, right the day after he would be elected would be saying, ‘Well, we’re going to impeach him.’”
