Johnson confirmed that it will move forward. Or perhaps it won’t.

The Biden “impeachment inquiry” has held no more hearings in the month since the first one. And, by his own admission, Comer doesn’t want to. “I don’t know that I want to hold any more hearings, to be honest with you,” Comer said while speaking to reporters on Capitol Hill last week. He complained that it was hard to keep members present for hours on end, given that so many had other commitments.
