The Put-Up-Or-Shut-Up moment.
Parade of foolish Congressional Committe Chairpersons comes to a screeching halt when their bluff gets called:
Here’s a video of Representative Jared Moskowitz calling the two Republican committee chairpersons’ (Reps Jordan and Comer) bluff at a session on the proposed impeachment of President Biden.
A Democrat makes the motion to impeach Biden and a Republican refuses to second the motion.

I absolutely love Mr. Moskowitz. If there was a category for excellence in shaming, he would get a Nobel prize for making fools of Comer and all his minions. He represents the some of the best of the remaining segment of Congress that has integrity and honor. He proves it every time he opens his mouth on this committee.
