That's not really what he said. He pointed out that Kadzik's office serves little more than a ceremonial function in the Justice Department. It's an important role because there are serious legal issues whenever the Department communicates with Congress about ongoing investigations, but it has nothing to do with any oversight of these investigations.
That's what I got out of Trey Gowdy's comments yesterday.
He stated he doesn’t make the decisions and that “he is not a decision maker, he is a messenger.” He stated he has no problems with him because of that. At roughly the five minute mark.
