The leaker broke the law, what was described in the whistleblower complaint is not what happened in the phone call, how do we know that? We have the transcript of the call. Is that the precedent you want to set? That if you don't like a President you can leak confidential material? Even when there is no crime committed?
A moral obligation? So Trump has a moral obligation to investigate Biden?
Don't get to make the rules? A presidents phone call with another is confidential, that isn't making up the rules, it is the law. The transcript is public, there's no second guessing what happened on the call.
Yea, there is a line, if you set up an incoming President elect, instruct to abuse FISA warrants, push a false story that leads to an American getting arrested to cover for you.
Talking to an ally about an investigation into a former VP, that as you just stated we have a moral obligation to do, isn't an impeachable offense. There is no high crime or misdemeanor there.
You don't mind hurting America as long as you get what you want though, you made that clear.
