I've always enjoyed reading and listening to Jonathan Turley. He's been called by the Republicans and imo is doing very well arguing about why impeachment is problematic in this case.

He is and has been warning about the speed at which the Democrats have been moving at this. He also is criticizing both abuse of power and obstruction of justice in this case.

He stated that he is a Madisonian scholar, mostly in favor of the Congress over the Executive. He is upset that in this case, the Congress is actually the branch most involved with abuse of power. From the way the hearings, secrecy, threats against the President if he appeals to the courts, demands for enormous amounts of documents in too short duration of time-including appeals regarding executive privilege.

I like him, likely because that while he doesn't care for the President, he cares more about the institutions that are being injured dramatically if not destroyed.
