Impeach Congress, too!
Hell yes. And an interesting clause in the impeachment wording is that it takes a 2/3 vote of the Senators PRESENT to impeach. Doesn’t mention an quorum requirement. Just 2/3 of the Senators PRESENT.
I can visualize a scenario where plenty of ‘rat Senators would not dare to show their treasonous hides in the Capitol, and would be elsewhere when the vote was held.
