WASHINGTON (AP) — Top national security officials for President Donald Trump, including his defense secretary, texted plans for upcoming military strikes in Yemen to a group chat in a secure messaging app that included the editor-in-chief for The Atlantic, the magazine reported in a story posted online Monday. The National Security Council said the text chain “appears to be authentic.”
Trump initially told reporters he was not aware that the highly sensitive information had been shared, 2 1/2 hours after it was reported. He later appeared to joke about the breach.

The material in the text chain “contained operational details of forthcoming strikes on Iran-backed Houthi-rebels in Yemen, including information about targets, weapons the U.S. would be deploying, and attack sequencing,” editor-in-chief Jeffrey Goldberg reported.
It was not immediately clear if the specifics of the military operation were classified, but they often are and at the least are kept secure to protect service members and operational security. The U.S. has conducted airstrikes against the Houthis since the militant group began targeting commercial and military vessels in the Red Sea in November 2023.
Just two hours after Goldberg received the details of the attack on March 15, the U.S. began launching a series of airstrikes against Houthi targets in Yemen.
The National Security Council said in a statement that it was looking into how a journalist’s number was added to the chain in the Signal group chat. In addition to Defense Secretary Pete Hegseth, it included Vice President JD Vance, Secretary of State Marco Rubio and Tulsi Gabbard, Trump's director of national intelligence.
Goldberg said he received the Signal invitation from Mike Waltz, Trump's national security adviser, who was also in the group chat.
Hegseth in his first comments on the matter attacked Goldberg as “deceitful” and a “discredited so-called journalist” while alluding to previous critical reporting of Trump from the publication. He did not shed light on why Signal was being used to discuss the sensitive operation or how Goldberg ended up on the message chain.
“Nobody was texting war plans and that’s all I have to say about that,” Hegseth said in an exchange with reporters after landing in Hawaii on Monday as he began his first trip to the Indo-Pacific as defense secretary.
Trump on Tuesday in a brief interview with NBC News' Garrett Haake downplayed the incident as “the only glitch in two months" of his administration "and it turned out not to be a serious one.”
White House press secretary Karoline Leavitt on Tuesday said in post on X that no war plans were discussed and that “No classified material was sent to the thread.”
Leavitt said on Monday the president still has the “utmost confidence” in Waltz and the national security team. Trump told NBC News on Tuesday that Waltz "has learned a lesson, and he’s a good man.”
Earlier Monday, Trump told reporters: “I don’t know anything about it. You’re telling me about it for the first time.” He added that The Atlantic was “not much of a magazine.”
By early evening, the president jokingly brushed it aside. He amplified a social media posting from Elon Musk spotlighting a conservative satirical news site article with the cutting headline: “4D Chess: Genius Trump Leaks War Plans to ‘The Atlantic’ Where No One Will Ever See Them."
Government officials have used Signal for organizational correspondence, but it is not classified and can be hacked. Privacy and tech experts say the popular end-to-end encrypted messaging and voice call app is more secure than conventional texting.
Leavitt said the White House counsel’s office has provided guidance to Trump’s top officials on a number platforms to communicate as safely and efficiently as possible.
The sharing of sensitive information comes as Hegseth's office has just announced a crackdown on leaks of sensitive information, including the potential use of polygraphs on defense personnel to determine how reporters have received information.
Sean Parnell, a spokesman for Hegseth, did not immediately respond to requests for comment on why the defense secretary posted operational plans on an unclassified app.
The administration's handling of the highly sensitive information was swiftly condemned by Democratic lawmakers. Senate Democratic leader Chuck Schumer called for a full investigation.
“This is one of the most stunning breaches of military intelligence I have read about in a very, very long time,” Schumer, a New York Democrat, said in a floor speech Monday afternoon.
“If true, this story represents one of the most egregious failures of operational security and common sense I have ever seen,” said Sen. Jack Reed of Rhode Island, the top Democrat on the Senate Armed Services Committee, in a statement.
He said American lives are “on the line. The carelessness shown by Trump’s Cabinet is stunning and dangerous. I will be seeking answers from the Administration immediately.”
Rep. Jim Himes of Connecticut, the top Democrat on the House Intelligence Committee, said in a statement that he was “horrified” by the reports.
Himes said if a lower-ranking official “did what is described here, they would likely lose their clearance and be subject to criminal investigation. The American people deserve answers,” which he said he planned to get at Wednesday’s previously scheduled committee hearing.
Some Republicans also expressed concerns.
Sen. Roger Wicker, the Mississippi Republican who chairs the Senate Armed Services Committee, told reporters Monday, “We’re very concerned about it and we’ll be looking into it on a bipartisan basis.”
Reed said he would be speaking with Wicker about what the committee will do to “follow up” on the Signal leak. And Senate Majority Leader John Thune said he wants to learn more about what happened.
“Obviously, we got to to run it to the ground, figure out what went on there,” said Thune, a South Dakota Republican.
Republican House Speaker Mike Johnson offered a notably forgiving posture.
“I think it would be a terrible mistake for there to be adverse consequences on any of the people that were involved in that call," Johnson said. "They were trying to do a good job, the mission was accomplished with precision."
The handling of national defense information is strictly governed by law under the century-old Espionage Act, including provisions that make it a crime to remove such information from its “proper place of custody” even through an act of gross negligence.
The Justice Department in 2015 and 2016 investigated whether former Secretary of State Hillary Clinton broke the law by communicating about classified information with her aides on a private email server she set up, though the FBI ultimately recommended against charges and none were brought.
In the Biden administration, some officials were given permission to download Signal on their White House-issued phones, but were instructed to use the app sparingly, according to a former national security official who served in the Democratic administration.
The official, who requested anonymity to speak about methods used to share sensitive information, said Signal was most commonly used to communicate what they internally referred to as “tippers” to notify someone when they were away from the office or traveling overseas that they should check their “high side” inbox for a classified message.
The app was sometimes also used by officials during the Biden administration to communicate about scheduling of sensitive meetings or classified phone calls when they were outside the office, the official said.
The use of Signal became more prevalent during the last year of the Biden administration after federal law enforcement officials warned that China and Iran were hacking the White House as well as officials in the first Trump administration, according to the official.
The official was unaware of top Biden administration officials — such as Vice President Kamala Harris, Defense Secretary Lloyd Austin and national security adviser Jake Sullivan — using Signal to discuss sensitive plans as the Trump administration officials did.
Signal’s encryption protocol is open source, meaning that it’s freely available for anyone to inspect, use or modify. The encryption protocol is also used by another popular chat service, social media company Meta’s WhatsApp platform.
Some of the toughest criticism targeted Hegseth, a former Fox News Channel weekend host. Sen. Tammy Duckworth, an Iraq War veteran, said on social media that Hegseth, “the most unqualified Secretary of Defense in history, is demonstrating his incompetence by literally leaking classified war plans in the group chat.”
In the chain of messages, Vance questioned whether Americans would understand the importance of strikes that came with the risk of “a moderate to severe spike in oil prices” and if the timing of the operation might be a “mistake.”
“I am willing to support the consensus of the team and keep these concerns to myself,” Vance argued. “But there is a strong argument for delaying this a month, doing the messaging work on why this matters, seeing where the economy is, etc.”
Vance also made the case that Europe would benefit much more than the U.S. by the action aimed at decimating the Houthis and securing Red Sea shipping lanes.
“If you think we should do it let’s go. I just hate bailing Europe out again,” Vance said in a back-and-forth with Hegseth.
“I fully share your loathing of European free-loading. It’s PATHETIC,” Hegseth replied. He added, “I think we should go.”
The vice president’s communications director, William Martin, released a statement downplaying the debate. He said Vance “unequivocally supports this administration’s foreign policy.”
Leavitt is one of three Trump administration officials who face a lawsuit from The Associated Press on First and Fifth Amendment grounds. The AP says the three are punishing the news agency for editorial decisions they oppose. The White House says the AP is not following an executive order to refer to the Gulf of Mexico as the Gulf of America.
