It's hilarious. The House helped Trump throw a stink bomb into the Senate and Republicans don't know which way to run.
Its always amazing hearing republican politicians complain about Trump when he does something foolish.
The GOP saw how petty and vindictive Trump can be (e.g. firing inspectors general). They saw he was willing to lie (everything from the size of his inauguration crowd, to Alabama being in the path of a hurricane) and engage in criminal activity (Trump University, blackmail/bribe Ukraine into investigating Biden). Its obvious that Trump is an incompetent narcissist con-artist.
Yet republican congress critters did everything they could to enable Trump. They voted to confirm his cabinet members (even the ones that were clearly not competent for the job) and his judges. And when he was impeached (and they had the chance to finally get rid of him), they lined up to say "Yeah, no problem if you break the law".
And NOW they complain about Trump not playing by the rules. What did you expect? They are like the guy who gets a pet alligator, and then gets surprised when it ends up biting their leg off.
