United States government group chat leaks

From March 11 to 15, 2025, a group of United States national security leaders made a group chat on the Signal app about the military operations in Yemen. The members were Vice President JD Vance, White House staff, three Cabinet secretaries, and the leaders of two Intelligence Community agencies. That happened hours before the attacks. Signal-gate [and Signalgate] is another name of the controversy.

Mike Waltz accidentally added Jeffrey Goldberg, the editor-in-chief for _The Atlantic_. Pete Hegseth, the Secretary of Defense used the group chat to share information about the airstrikes in Yemen.

The kind of information that was shared (in group chat), is called _concept of operation_. However, some media say that _war plans_ were leaked.

## People changing jobs (or positions) after the leaks

In mid-April, Dan Caldwell (advisor) was put on administrative leave and was terminated. He was one of the people, that was on _group chat_.

Media said (in May), that Mike Waltz no longer had his job. Earlier, Waltz said that he takes responsibility for the leak. On May 1, 2025, Waltz was nominated by President Trump as the nominee for U.S. Ambassador to the United Nations, replacing Congresswoman Elise Stefanik after her nomination on March 27, 2025.

Waltz was confirmed as the 32nd U.S. Ambassador to the United Nations by the U.S. Senate on September 19, 2025 by a vote of 47-43 and was sworn in the next day. He took office on September 21st after presenting his credentials to UN Secretary-General António Guterres and was also confirmed by the Senate as the United States representative to the UN General Assembly on September 29, 2025.

## Response

On April 3, the Pentagon started an investigation after a request from the United States Senate Committee on Armed Services.

The Guardian says the White House information technology office had a "forensic review" on the leaks and discovered that Waltz's phone saved Goldberg's number as Brian Hughes.
