Take on executive privilege

Trump was hoping he's be able to smooth talk Biden into some kind of non existent executive privilege for former presidents but sadly for Trump -and luckily for democracy- Biden didn't bite.
What was more shocking was that Steve Bannon tried to use the same thing which was odd being that he was neither the president or actually a formal advisor to one on January 6th. The two seem to have convoluted executive privilege with a pardon and the two really have nothing to do with one another
