It's possible that Weldon is playing a game and putting a public face on. He may not be certain that the Co-Chairs weren't briefed, but if he gets their support for other things and keeps pushing for Congressional hearings, they'll have to testify under oath.
FWIW, that wasn't the impression I got from the short bit I saw. But I hope you're right.
