'Signalgate' Group Chat Revealed Precise Attack Timeline, Surveillance of Target

The now-famous group chat made up of high-ranking Trump administration national security officials and a journalist included a precise timeline of U.S. bombing of Houthi targets in Yemen, and revealed one of the targets of the attack was under surveillance, according to a release of the entire text chain The Atlantic published Wednesday.

Despite the newly revealed details of the leaked chat, administration officials, including President Donald Trump himself, continued to downplay the seriousness of the breach, and Republicans in Congress refused to join Democrats in calls for Defense Secretary Pete Hegseth to step down.

Administration officials argued the texts lacked key information and that the “attack plans” revealed in the chat were less damaging than “war plans,” the term Editor-in-Chief Jeffrey Goldberg used to refer to information he’d decided to withhold for national security reasons. Trump aides also implied the magazine – which has endorsed Trump’s opponent in each of his elections – was spinning the entire episode to discredit the administration.

What’s been dubbed “Signalgate” began when The Atlantic on Monday published a stunning account by Goldberg of his apparently accidental inclusion in a group chat on the messaging app Signal, titled “The Trump Administration Accidentally Texted Me Its War Plans.”

The others in the chat were senior administration officials discussing the upcoming war operation.

Administration leaders on Tuesday denied, including in testimony before Congress, that the chat contained classified information. The magazine then published a report Wednesday by Goldberg and staff writer Shane Harris that purported to include virtually the entire transcript of the chat until Goldberg’s voluntary exit.

The administration position was inconsistent with the screenshots published in The Atlantic of detailed and explicit messages in the chat. At the Capitol, concerns were raised even among the administration’s usually obsequious GOP allies in Congress, with U.S. Senate Armed Services Committee Chairman Roger Wicker saying the information in the chat should have been classified.

“The information as published recently appears to me to be of such a sensitive nature that, based on my knowledge, I would have wanted to classify it,” Wicker, a Mississippi Republican, told reporters on the Hill Wednesday.

Attack Details Revealed

In the initial story, Goldberg reported National Security Advisor Michael Waltz on March 11 added the journalist to a group chat on Signal that included Vice President J.D. Vance, Hegseth, Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard, CIA Director John Ratcliffe, Waltz and others.

Goldberg in the first story withheld details of the chat that he said could have compromised intelligence-gathering and military operations.

But after a day of administration figures claiming the Signal chat did not reveal classified material, while smearing Goldberg, the magazine published the entire thread with one redaction: the name of Ratcliffe’s chief of staff, at the request of a CIA spokesperson.

The unredacted messages show Hegseth shared plans of the bombing campaign about 30 minutes before the first planes took off on March 15 and two hours before the start of the window of opportunity for hitting a target.

“TEAM UPDATE,” Hegseth wrote in the chat on the day of the strike, according to the Atlantic’s Wednesday story. “TIME NOW (1144et): Weather is FAVORABLE. Just CONFIRMED w/CENTCOM we are a GO for mission launch.”

In the same message, Hegseth laid out a timeline of the attack, including confirmation that a target was at his expected location.

“Target Terrorist is @ his Known Location so SHOULD BE ON TIME,” Hegseth wrote.

He also noted that the mission’s operational security was “clean.”

Two hours and 15 minutes later, Waltz told the group that bombs had destroyed a building where the Houthi “top missile guy” was thought to be present.

“The first target – their top missile guy – we had positive ID of him walking into his girlfriend’s building and it’s now collapsed,” Waltz wrote.

Tuesday Denials Led to Publishing

At a previously scheduled U.S. Senate Intelligence Committee hearing Tuesday, Gabbard said that no classified information was discussed in the chat.

Trump echoed that message and Hegseth said, “Nobody was texting war plans and that’s all I have to say about that.”

White House press secretary Karoline Leavitt wrote on social media:

“Here are the facts about his latest story: 1. No ‘war plans’ were discussed. 2. No classified material was sent to the thread. 3. The White House Counsel’s Office has provided guidance on a number of different platforms for President Trump’s top officials to communicate as safely and efficiently as possible.”

Gabbard and Ratcliffe told the Senate Intelligence Committee they did not recall specific weapons systems or the timing of the operation being discussed in the chat.

But the transcript published by The Atlantic showed Hegseth’s down-to-the-minute timeline of the launch of F-18 aircraft.

The denials led to the magazine’s decision to publish the full transcript Wednesday, Goldberg and Harris wrote.

“The statements by Hegseth, Gabbard, Ratcliffe, and Trump — combined with the assertions made by numerous administration officials that we are lying about the content of the Signal texts — have led us to believe that people should see the texts in order to reach their own conclusions,” they wrote.

“There is a clear public interest in disclosing the sort of information that Trump advisers included in nonsecure communications channels, especially because senior administration figures are attempting to downplay the significance of the messages that were shared.”

‘No names. No targets.’

But Hegseth and other administration officials continued to deny the growing controversy was serious Wednesday.

“So, let’s (sic) me get this straight,” Hegseth wrote on X Wednesday. “The Atlantic released the so-called ‘war plans’ and those ‘plans’ include: No names. No targets. No locations. No units. No routes. No sources. No methods. And no classified information.

“Those are some really shitty war plans.”

Waltz posted a similar message.

“No locations,” he wrote. “No sources & methods. NO WAR PLANS. Foreign partners had already been notified that strikes were imminent. BOTTOM LINE: President Trump is protecting America and our interests.”

White House Counselor Alina Habba told reporters shortly after the second Atlantic story posted on Wednesday morning the issue had been overblown.

“We stand by Mike Waltz; he's doing a tremendous job,” she said, according to a White House pool report. “I think this is a distraction."

Bipartisan Call for Investigation

Leading members of Congress, though, were treating the matter with more seriousness.

Wicker said he and Armed Services ranking Democrat Senator Jack Reed of Rhode Island had agreed on next steps, which included a letter to the administration asking for an expedited inspector general report on the matter.

He also said they were requesting “a senior person” come to a secure facility on Capitol Hill to provide a classified briefing to the committee to confirm the reporting was accurate.

Asked what the consequence should be for Hegseth if the transcript of the chat was accurate, Wicker took a forgiving tone.

“I make a lot of mistakes in my life,” he said. “And I’ve found that it’s best when I just own up to it and say ‘I’m human, I made a mistake.’ And I’m glad in this case no real damage was done. I think that’s probably the approach of the administration right up to the president.”

He also said that no targets or specific timing were mentioned.

Alaska Republican Senator Lisa Murkowski, a moderate who has voiced criticism of Trump more often than most GOP colleagues, wrote in an X post Wednesday that the incident should be a “wake-up call” to prioritize operational security.

“I am appalled by the egregious security breach from top administration officials,” she wrote. “Their disregard for stringent safeguards and secure channels could have compromised a high-stakes operation and put our servicemembers at risk. I hope this serves as a wake-up call that operational security must be a top priority for everyone—especially our leaders.”

Dems Urge Hegseth’s Resignation

Many Democrats went further, calling for Hegseth to resign over the use of an unclassified messaging platform to discuss impending military action.

Gabbard and others noted the Defense secretary can decide what information is classified to argue that the chat did not include classified information.

But critics said whether or not the information was technically classified, its disclosure would put service members at greater risk.

“Advance strike times are sensitive and classified because they put American military directly at risk,” Intelligence Committee Vice Chairman Mark Warner, a Virginia Democrat, wrote on social media Wednesday. “The Secretary of Defense was blasting them out to unknown numbers over unclassified channels. It’s sloppy, careless, and dangerous. He should resign.”

Warner spokeswoman Rachel Cohen added that, despite the administration's denials, the information revealed in The Atlantic would compromise intelligence sources and methods.

“They can keep repeating this but it’s not true,” she wrote, responding to Hegseth’s post. “Those messages, as released by the Atlantic, are source revealing, and include targeting and weapons information that would have, at the very least, been considered at the ‘secret’ classification level.”

The top Democrats in the U.S. House and U.S. Senate, Hakeem Jeffries and Chuck Schumer, both of New York, also called for Hegseth to lose his job.

“The secretary of Defense should be fired immediately if he’s not man enough to own up to his mistakes and resign in disgrace,” Jeffries said on MSNBC Wednesday.

“I agree he should be fired,” Schumer told reporters at the Capitol.
