Sometimes I wonder about that. Why not can the lot of them. We are never going to get any favorable press anyway,what is the down side?
Losing a lot of support in Congress. Ryan is just itching to allow an impeachment committee, even while pretending to be neutral about it. The committee would just continue Mueller's work, maybe even have him give what he's got to date, which is probably only stuff he got about Trump's businesses.
His legislative agenda would pay a big price. The media would not stop talking about it for months.
I think if he laid the groundwork for it, had a bunch of rallies to talk about Mueller and what he is doing and maybe a few oval office addresses, he might be able to keep it from being so bad. The best thing he could do is get the prosecutions of Hillary, Comey, DWS, going for real. That would keep the opposition off balance.
