2. We know he violated both the foreign and domestic emoluments clauses of the Constitution
3. We know he violated FEC rules (per the Cohen case)
4. We know he obstructed justice many times (per Mueller)
6. We know he violated the law requiring him to turn over his taxes to the Congress
These are all clear cut cases where there are mountains of proof and where prosecution of anyone else would take place.
@RepAdamSchiff in my view is a very good man, one of the very best public servants we have in our Congress. This is not an attack on him.
