Sure, but once someone is confirmed, the Senate can't do jack shit. What's to stop someone from getting up there, raising his or her right hand, saying all the right and correct things, and then doing whatever he or she wants once AG?
Again, Jeff Sessions said he was recusing himself over all Russian related matters, but then was involved in Comey's firing, which, Trump himself admitted, was because of Russia. Did the Senate suddenly revoke Session's confirmation? Did they decide to impeach him? No, they didn't do anything.
