I have a quite different view. They are not trying to make him quit in disgust.
The power wielded by President Trump is more than adequate to destroy the House of Cards that Hillary clinton and the DNC emails made vulnerable. The Special Counsel investigation is a threat, black mail if you will. Trump is threatened to back off or we will expose all.
Comparing the two positions, Trump has the stronger.
Well if you look at The President’s speech last night he was going directly after the Clintons. You may have something there. When he fired Comey they interpreted that as reopening the investigation into the Clintons. It is amazing the corruption of the Clintons. The tentacles must reach far and wide. They are protecting them with everything they’ve got. An honest investigation of the Clintons is probably all we need to do to almost completely drain the dc swamp and they know it.
