What Did the President Know, and When…?

More on the Chat that Shook the World:
Administration officials said Trump was frustrated by the episode, and was directing his ire at Waltz. But it wasn’t immediately clear if he would move to oust his national-security adviser, the officials said.
Trump asked aides on Monday how Waltz could be so sloppy, one of the officials said.
The Signal chat group that discussed the planned strikes against the Houthis listed 18 users including Waltz, Hegseth, Vance, Central Intelligence Agency Director John Ratcliffe, Director of National Intelligence Tulsi Gabbard, Treasury Secretary Scott Bessent, special envoy Steve Witkoff and a user identified as “MAR,” which appeared to be Secretary of State Marco Rubio.
Such conversations would normally happen in the White House Situation Room or over secure government communications networks designed for top-secret information. Signal is a free app run by a U.S. nonprofit.
The use of the Signal chat comes as the Trump administration has said it is trying to protect classified information by clamping down on leaks.
I would be surprised that no one noticed when Jeff Goldberg left the chat, but then these people are completely inept. Goldberg says he let the White House know this morning at 9am, which appears to have been the first inkling that anything was amiss. Goldberg’s interview with David Graham is worth your time if you can get past the paywall. Hegseth’s decision to share details of the war plan leaves him more exposed than any of the rest of the group (except for Waltz), but I would imagine that Trump must be furious with all of them. This is not, to say the least, reassuring about the administration’s commitment to cyber-security.
