How you going to get two-thirds of the Senate to convict? Hell if we could get just the GOP members of the Senate to play ball, Trump could simply fire him in his own without fear of getting impeached himself.
“How you going to get two-thirds of the Senate to convict?”
Just making them vote would drag a lot of sordid facts out in public.
Then if more dirt comes out later, you can hang their vote on them.
You don't need to convict. Trump can fire him if the House impeaches.
