Are you sure? What if they just vote without an official investigation? Is there really anything keeping them from changing the rules specifically to get President Trump.
Of course, in that case the senate could probably refuse to recognize it. But would they have the guts to do so? Or would they feel compelled to follow their own rules in order to maintain their dignity?
Ok, you got me. I’m not sure of anything any more.
But, Trump’s position has been that if the Dems want subpoenas to be honored, GOP requests for subpoenas will have to be honored too.
Could they vote, and change the rules? Sure, but it would look bad.
