Let's turn to Lawfare, and Benjamin Wittes. He is learned. He is sober. He is intelligent. He knows his shit! What say you Mr. Wittes? "It's Time: Congress Needs to Open a Formal Impeachment Inquiry!" And what are the articles?
1. His abuses of power, most obviously exemplified by his conduct with respect to the investigations into his campaign’s collusion with Russia.
2. His failures of moral leadership.
3. His abandonment of the basic duties of his office.
Also, of course, and maybe most damning of all, he is a Total Dick! Impeach the Freaking Dick!
