On Monday, Goldberg claimed that high-ranking US officials had accidentally included him in the chat to discuss strikes on Yemeni movement Ansar Allah, also known as the Houthis. He said the group, called "Houthi PC small group," was hosting an engaging political discussion involving accounts under the names of Secretary of Defense Pet Hegseth, US Vice President JD Vance, and National Security Advisor Mike Waltz.
"Well, look, a staffer wasn't responsible. And look, I take full responsibility. I built the group, my job is to make sure everything's coordinated," Waltz said in an interview with Fox News.
Waltz also ruled out the possibility that the journalist was intentionally added to the group, adding that he "looked like someone else" in the chat.
"I just talked to Elon [Musk] on the way here. We've got the best technical minds looking at how this happened. But I can tell you for 100% I don't know this guy," he added.
