Trump Just Guaranteed His Own Impeachment
Donald Trump just canceled a trip by Nancy Pelosi and a congressional delegation after she already had boarded a bus to leave. They exposed where they were going which included the volatile country of Afghanistan. This is a breach of security protocol.
Trump and his GOP allies don't seem to understand that they've just made a political fight personal. So let me explain it to them. You've cancelled their trip while they were already heading out and you created a potential risk to their safety. They are going to shiv the living fuck out of you. There is no more playing nice. Sure in public they'll still be civil, but expect the investigations to intensify. Anything that hasn't been leaked yet will. In any political battle where they have leverage, they'll use it.
When the day comes to impeach Trump they will, and they'll stage an all out push to crush him in the senate. As for whether he will be allowed to resign and not be prosecuted, I think we're a little past that point. Trump and the Republicans have no idea how deep the hole is that they are already in, and they have no idea how to stop digging further.
