BUT IS NOT OBLIGATED TO!
This is very debatable.
....
Mitch has come out and said if the House impeaches, he would have no choice but to try Trump. ....
Interesting you would say that. I just heard Mitch McConnel Fox News say that if Trump was "impeached" with the Pelosi method he wouldn't pay any attention to it. Sorry, I didn't pay enough attention to it to have an exact quote.
BUT IS NOT OBLIGATED TO!
When it comes to the impeachment and ethics stuff, your stance should not be swayed based on which party is in power.
And there we are. Hypocritical stern moralizing about how the House can break their traditional rules, but the Senate cannot.
Wrong on that, buddy. Gamble on that outcome, you are going to lose, and lose bad.
