Go for one better. Do what Lamar Alexander , Governor elect of Tennessee , did to stop a pardon scandal: catch the crooks off guard by swearing in early . That way we could get both Hillary and Obama some matching orange jump suits!
The 20th amendment states noon on Jan 20th ,, no way to get in before then and catch them before they issue pardons... although I would make it plain that if by issuing pardons the president expects to insulate himself against any future charges that it will in fact have the opposite effect.
