I am talking about upholding a legally binding oath. I am talking about upholding the laws on the books, not some hypothetical here.
They have a duty. A legal obligation to the constitution.
Period.
You are delusional...if you were at the founding you would have sunk the constitution because the slavery issue was not dealt with. The terms of high crimes and misdemeanors means what the congress says it means. Because congress has ceded power to the president over the years you would be better off complaining about all since Wilson onward....maybe even teddy Roosevelt onward.
Again cite where the constitution says they must....it doesn’t which means they are not required. Defense of the country and the constitution is done in many ways not just impeachment.
Just as my boss says you can be right all the way out the door and can say anything you wish on your last day.
