Actually it is - if they decide that all of that is a felony - It’s disqualification for holding the office of president.
There is no felony disqualification for the President. Constitution says you have to be 35 and a natural born citizen. Beyond that, you can be a felon. It is irrelevant anyway, because the only recourse for a criminal accusation against the President is impeachment. Congress can ignore a felony, or impeach for a misdemeanor. It is a political question more than a legal question. After a president is impeached and convicted in the Senate, he would be open to actual criminal charges by federal or state prosecutors.
