The Information Security Administration!

After receiving the Waltz text related to the “Houthi PC small group,” I consulted a number of colleagues. We discussed the possibility that these texts were part of a disinformation campaign, initiated by either a foreign intelligence service or, more likely, a media-gadfly organization, the sort of group that attempts to place journalists in embarrassing positions, and sometimes succeeds. I had very strong doubts that this text group was real, because I could not believe that the national-security leadership of the United States would communicate on Signal about imminent war plans. I also could not believe that the national security adviser to the president would be so reckless as to include the editor in chief of The Atlantic in such discussions with senior U.S. officials, up to and including the vice president…
At 11:44 a.m., the account labeled “Pete Hegseth” posted in Signal a “TEAM UPDATE.” I will not quote from this update, or from certain other subsequent texts. The information contained in them, if they had been read by an adversary of the United States, could conceivably have been used to harm American military and intelligence personnel, particularly in the broader Middle East, Central Command’s area of responsibility. What I will say, in order to illustrate the shocking recklessness of this Signal conversation, is that the Hegseth post contained operational details of forthcoming strikes on Yemen, including information about targets, weapons the U.S. would be deploying, and attack sequencing.
The only person to reply to the update from Hegseth was the person identified as the vice president. “I will say a prayer for victory,” Vance wrote. (Two other users subsequently added prayer emoji.)
According to the lengthy Hegseth text, the first detonations in Yemen would be felt two hours hence, at 1:45 p.m. eastern time. So I waited in my car in a supermarket parking lot. If this Signal chat was real, I reasoned, Houthi targets would soon be bombed. At about 1:55, I checked X and searched Yemen. Explosions were then being heard across Sanaa, the capital city.
I went back to the Signal channel. At 1:48, “Michael Waltz” had provided the group an update. Again, I won’t quote from this text, except to note that he described the operation as an “amazing job.” A few minutes later, “John Ratcliffe” wrote, “A good start.” Not long after, Waltz responded with three emoji: a fist, an American flag, and fire. Others soon joined in, including “MAR,” who wrote, “Good Job Pete and your team!!,” and “Susie Wiles,” who texted, “Kudos to all – most particularly those in theater and CENTCOM! Really great. God bless.” “Steve Witkoff” responded with five emoji: two hands-praying, a flexed bicep, and two American flags. “TG” responded, “Great work and effects!” The after-action discussion included assessments of damage done, including the likely death of a specific individual. The Houthi-run Yemeni health ministry reported that at least 53 people were killed in the strikes, a number that has not been independently verified.
Evidently senior administration players accidentally included Jeffrey Goldberg on a Signal chat group.
I have never seen a breach quite like this. It is not uncommon for national-security officials to communicate on Signal. But the app is used primarily for meeting planning and other logistical matters—not for detailed and highly confidential discussions of a pending military action. And, of course, I’ve never heard of an instance in which a journalist has been invited to such a discussion…
All along, members of the Signal group were aware of the need for secrecy and operations security. In his text detailing aspects of the forthcoming attack on Houthi targets, Hegseth wrote to the group—which, at the time, included me—“We are currently clean on OPSEC.”
