Really this is a question about blanket pardons, whether they're valid. Hopefully that gets challenged and cleared up sooner than later.
(It's also about what a pathetic loser Trump is spitting out dumb lines he thinks will get him laughs, and his sycophants that force laughs at lame jokes to make him happy)
But there's hardly corrupt intent here. Wanting attention or political pats on the head are pretty normal.
