who was being impeached or on trial, would I be able to specify ‘no witnesses’, or harass someone who spoke?  Guess I don’t understand 1. how impeachment works, and/or why some people seem to get a pass no matter what they do.

From the NYTimes:

Lt. Col. Alexander Vindman, a decorated Iraq war veteran who was a prominent witness in the Trump impeachment inquiry, said he would retire from the Army after the White House objected to his promotion.

We are on such a powerful road to ruin in this country, and no one with any kind of power seems to be actually doing anything to change that.  Puzzled R Us.
