Days before U.S. fighter jets took off from the aircraft carrier Harry S. Truman in the Red Sea for strikes against the Iran-backed Houthis in Yemen, a security breach with potentially catastrophic consequences for the U.S. military.

Details of the U.S. war plans shared, in real time, with the Atlantic's editor-in-chief, Jeffrey Goldberg by accident on unclassified commercial messaging app signal

“I assumed that I was being spoofed or hoaxed or being included in some kind of disinformation campaign bc it was too improbable to me that they would have such poor operation security as to inadvertently invite the editor of the Atlantic into a national security discussion about the timing of a bombing campaign,” said Goldberg. 

But it was deadly serious, Goldberg said he was added by a user, National Security Advisor Mike Walz, to a group chat including the Vice President, the Secretary of State, the Defense Secretary, the CIA Director and the Director of National Intelligence. 

Sharing precise information about weapons packages, targets and timing.

Shocking Senate Intelligence Vice Chair Mark Warner.

“Holy crap. I mean when this level of detail is shared on a nonclassified network, and this isn't the first time we've seen this sloppiness from this administration. Early on, there were a couple 100 CIA agents whose identities were exposed,” said Warner. 

Goldberg said at one point the Vice President called the timing of the attack on the Houthis, who've been striking international ships in the Red Sea for two years, a mistake because it conflicts with the President's message to end the war in Ukraine.

This chat was very substantive, there was disagreement among some of the principles, JD Vance suggested in this conversation that not only disagreed with the President but also felt the President didn't have all information or insight available

The National Security Council said the chat “appears to be authentic.” Adding, “We are reviewing how an inadvertent number was added to the chain,” and “There were no threats to our servicemembers or our national security.”

The President reacted tonight, saying, “The Houthis -- you mean the attack on the Houthis? Well, it couldn't have been very effective, because the attack was very effective. I can tell you that. I don't know anything about it.”
