I suspect some on this board may not understand how pardons work in the US. There are two broad classes of crimes: federal and state. Federal crimes are ostensibly those in which the federal government has an interest, such as banking crimes, immigration crimes, and crimes which take place on federal property, such as US National Parks. Any crime which occurs over state lines (or national boundaries) will generally be a federal crime, such as what Epstein and Maxwell did, transporting women and girls over state lines. Most run-of-the-mill crimes, such as murder, robbery, rape, and so on, will be state crimes.
The US President has a pretty much blanket ability to pardon or commute any federal crime. No one, not even Congress or the Supreme Court, can over-rule him. As Trump has discovered, he can even dish out pardons in exchange for cash donations (as far as I know, the first POTUS to do this, though), no matter how blatant or serious the crime. As for state crimes, the situation changes from state to state. In most states, governors have a similar ability to pardon or commute sentences. In some states, such as Texas, these pardons must be OK's by Parole/Pardon Boards, but since he appoints ALL of the members, that's not much of a check. In a small minority of states (nine), the governor has almost no say in pardons or commutations, and such decisions are made entirely by a Board of Paroles and Pardons (Idaho happens to be one of those nine states).
