Michael Waltz: “I certainly share the chairman's concern on really getting to the bottom of who is in charge, who is accountable.”

We’ve had 100 days of your leadership, with respect, with strength. It’s an honor to serve you in this administration, and I think the world is far better and far safer for it.

I took full responsibility for the problem.

I can tell you for 100 percent: I don’t know this guy… Wouldn’t know him if I bumped into him, if I saw him in a police lineup.

We're going to get to the bottom of it.
