But it is decided in a court of law if something is a felony or not. Impeachment is for 'high crimes and misdemeanors' while in office, not before being in office.
Do you want to see a Democratic Congress impeaching President Trump for overstating the value of Mar-a-Lago in 2010?
Covering up crimes while in office and using your administration to intercede to hide material facts of and stonewall the investigation is impeachable on its own merit.
“The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.”
Doesn’t say when the offenses occur.................
