This is very debatable.  

It's obvious the guys that wrote the constitution were very concerned about future presidents having too much power, abusing that power, being above the law,  and also other countries interfering in our election.

Anyone that's able to look at this situation without considering Trumps policies or his political opponents' policies surely sees that Trump is absolutely, without a doubt, checking all of these boxes.

But, the founders didn't say explicitly that the senate must have a trial.

Mitch has come out and said if the House impeaches, he would have no choice but to try Trump.  Who knows what he'll actually do though.  Maybe he'll hold the trial and then just immediately call a vote to end it.  Seems like the best move would be to have the trial as long as he's sure there won't be a conviction.

I just wish you guys that are Trump fans and fighting tooth and nail to defend everything he does (tecshare) would take a step back and realize you're arguing to give future presidents who have control of either the Speaker of the House or Senate majority leader to be a King.  That's all it takes.  The president and the leader of the House or Senate.  The President can't be indicted or impeached.  Can ask foreign countries for help and  do whatever the fuck they want.

When it comes to the impeachment and ethics stuff, your stance should not be swayed based on which party is in power.
