Presidential Pardon Power needs to be expanded and even to pardoning persons on stage charges.
That would indeed trigger a case before the Supreme Court but this is the time to test the case.
No thanks we don’t need the next 0bongo pardoning Mumia etc,
How much broader can it get? The President can literally pardon any person for any federal crime for any reason. The only exception to that is impeachment. What he can't do is pardon for state crimes.
