The Atlantic on Wednesday published screenshots of a Signal chat among President Trump's national security team that included timing and weapons details for an attack on Houthis in Yemen, adding to the storyline that has shocked Washington this week. The release came after Trump administ ration officials, including Defense Secretary Pete Hegseth, claimed war plans were never shared in the encrypted message group, which inadvertently included Atlantic Editor-in-Chief Jeffrey Goldberg. The screenshots also showed the 19 various members in the chat titled “Houthi PC small group.” In his reporting, Goldberg noted that he would not publish the name of the CIA official included in the group because that person is an active intelligence officer. Meet the other 18 members of the Houthi attack group chat: Jeffrey Goldberg Goldberg is the editor in chief of The Atlantic. He was mistakenly added to the group chat by national security adviser Mike Waltz and published the initial article detailing the use of Signal for planning the attack. Mike Waltz Waltz is the Trump administration’s national security adviser. He is the creator of the Signal group, and he praised the team after the strikes against the Houthis. He’s a former Florida congressman who served three full terms before resigning in January. In the fallout of the incident, Waltz said Tuesday they “made a mistake” and are “moving forward,” while also questioning how Goldberg was in the group. After the release of the screenshots, Waltz posted online that no locations, sources, methods or "WAR PLANS," were shared in the chat. He said foreign partners had already been notified and strikes were "imminent."  'Scott B' “Scott B” refers to Treasury Secretary Scott Bessent. He’s a billionaire hedge fund manager and investor and has defended President Trump’s global trade tariffs. 'Brian' Brian McCormack is a former energy consultant and the chief of staff for the National Security Council, serving under Waltz. Pete Hegseth Hegseth is the Defense Secretary and notably featured in the release of the second round of screenshots from The Atlantic. He detailed the timing of the launches, strikes and weapons used. He previously was a Fox News “Fox & Friends Weekend” co-host and served as an infantry officer in the Army National Guard. Hegseth was narrowly confirmed by the Senate after Vice President Vance broke a tie, with two Republicans voting against Hegseth in light of a litany of allegations. Dan Katz Katz is the chief of staff for Bessent, who identifies Katz as Treasury's contact in the chat. Joe Kent Kent is Trump’s nominee to run the counterterrorism center. He’s been acting as chief of staff for Director of National Intelligence Tulsi Gabbard. She identifies him as the point of contact for DNI in the chat. 'S M' “S M” was believed by Goldberg to be Stephen Miller, the White House deputy chief of staff for policy and one of Trump's most trusted aides. "MAR" “MAR” are Secretary of State Marco Rubio’s initials. His contact was included twice in the group chat, according to the screenshot published by Goldberg. The "MAR" contact identified a point of contact for State when asked in the chat. Mike Needham Needham is the counselor and chief of staff to Rubio. He is serving as a special adviser and consultant on foreign policy issues. He was named by "MAR" as the State Department's contact. John Ratcliffe Ratcliffe is the CIA director. On Tuesday and Wednesday, he has undergone questioning in Congress about the group chat. He confirmed he was part of the Signal group and said his use of the app to discuss the plans was authorized. Susie Wiles Wiles is the White House chief of staff. She’s a former political aide and Florida strategist. One of Trump’s closest allies, she helped run his 2024 presidential campaign. "TG" “TG” refers to Director of National Intelligence Tulsi Gabbard. She also faced questioning from Congress about the group chat, where she at first would not disclose if she was a member. Gabbard later admitted that it was a “mistake” for Goldberg to be added to the group. JD Vance Vance was part of the group chat and notably raised questions about Trump’s view on the Houthi attack. He also sharply criticized Europe for its role internationally and said he hates “bailing out the Europeans again.” Steve Witkoff Witkoff is the Trump administration’s special envoy and has been aiding the administration with international negotiations and prisoner swaps. Witkoff was in Russia at the time of the messages, sparking concern that the Kremlin could access classified U.S. information. The White House defended Witkoff’s conduct. Alex Wong Wong is Waltz’s aide, serving as the principal deputy national security adviser.  Walker Barrett Barrett is likely a senior staffer on Waltz's national security team. 'Jacob' It is unclear who "Jacob" is. ...read more read less
