I'm not sure if this counts specifically as violating his oath of office, but he should be impeached now.
When that fails, they can call for a vote of no confidence in the speaker since they changed the rules to not require a majority, if I understood some of the drama last year. This will also fail.
But it stops being a public pity party and starts to hold people accountable. I want people to sign off on this crap. We need to have it documented who the traitors are.
Right now its just people telling the guy who is undermining our countries security and stability "Hey, you can't do that!". Then watching him do it anyway.
Fuck that. Write down on a piece of paper "Donald Trump is a fascist dictator and must be impeached.". Then vote for it.
