If Trump gets Impeached everyone says there will be no trial in the Senate. What if Trump demanded a trial to clear his name? In an actual trial in the Senate, Trump will have the right to an attorney, the right to introduce evidence and cross examine witnesses. They can't deny him that right. Seeing that Trump is President I imagine he will have a great deal of evidence at his disposal. He also has the right to declassify anything he wants. It would be epic and the press would have to cover every minute of it.
So my guess is if Impeached? There will be a trial in the Senate. And it will be epic and poetic, because they started the whole thing.
