No controlling authority.

Ladies and gentlemen, your Attorney General and mine:

During those conversations, to my knowledge, I did not make decisions about who should or should not be asked to resign.

And it’s not that the guy who’s, y’know, in charge of the Department of Justice thinks he just dodged the bullet of a bad decision by saying, hey, look, I didn’t make the bad decision. It’s that he can’t even weasel without weaseling. “To my knowledge”? How on earth do you not know that you might have just made a decision? How can you be in doubt as to whether a decision had been made by you? —No, seriously. How?
