WRT lying - thought that the pres had to be above reproach and if caught lying could be impeached?
Yes and no. If you google "High Crimes and Misdemeanors", you get a variety of "crimes" like "conduct unbecoming" and "abuse of authority", "bad faith". It's ambiguous, subjective, vague, and malleable, and intentionally so. The founders could have required that an impeachment required a specific "crime", identified by a specific criminal code, be proved to a legal standard in order to qualify for impeachment, just like it is for a criminal conviction. They chose not to.
Impeachment is a political, not criminal process. It's a check by Congress on the Presidency. If enough of them think that Trump's lies are just getting too embarrassing to tolerate, they need not wait for him to actually commit a crime, be able to collect evidence, etc. It's the American version of a "No Confidence" vote, just like firing someone because everyone thinks they suck at their job as opposed to firing them "for cause" where you'd have to document embezzlement, drunkenness, tardiness, etc.
They can impeach him for his lies or his attitudes towards women or not liking his tie or his combover whatever the hell they want.
Conversely, they can choose to overlook any bad conduct that they want to. They don't HAVE to impeach him if they decide he's doing a good job.
Frankly this is the way it should be. You can't legislate stupid. Barring them proving that actual electoral fraud put him in office, he is President Trump by the will of the American people, who were fully aware of all his lies and stuck him in there anyway, so impeaching him for lying seems like a hard sell. Lots of folks love him in spite of or even because of his lying. Their votes count too.
We're a democracy. We get the leaders we deserve.
