The Founding Fathers were deliberately vague about what would constitute grounds for impeachment, saying only that a president can be impeached for “high crimes and misdemeanors,” which puts the definition of that open-ended phrase, in the case of president Trump, in the hands of the current House of Representatives now being led by Nancy Pelosi who was unable to attract a single Republican vote for her mere resolution to establish just the manner of process to pursue impeachment! Nervous Nancy is losing this heated political fight because she chose to conduct the inquiry (to this point) in secrecy, a Kangaroo Court not the way to convince the body politic that impeachment is merited!
