Pentagon chief Pete Hegseth shared sensitive Yemen war plans in second Signal chat: source

U.S. Defence Secretary Pete Hegseth shared details of a March attack on Yemen's Iran-aligned Houthis in a message group that included his wife, brother and personal lawyer, a source familiar with the matter told Reuters on Sunday.

The revelations of a second Signal chat raise more questions about Hegseth's use of an unclassified messaging system to share highly sensitive security details and come at a particularly delicate moment for him, with senior officials ousted from the Pentagon last week as part of an internal leak investigation.

In the second chat, Hegseth shared details of the attack similar to those revealed last month by The Atlantic magazine after its editor-in-chief, Jeffrey Goldberg, was included in a separate chat on the Signal app by mistake, in an embarrassing incident involving all of U.S. President Donald Trump's most senior national security officials.

The person familiar with the matter, who was speaking on condition of anonymity, said the second chat included about a dozen people and was created during his confirmation process to discuss administrative issues rather than detailed military planning.

The chat included details about the schedule of the airstrikes, the person said.

Hegseth's wife, Jennifer, a former Fox News producer, has attended sensitive meetings with foreign military counterparts, according to images publicly posted by the Pentagon.

During a meeting Hegseth had with his British counterpart at the Pentagon in March, his wife could be seen sitting behind him.

Hegseth's brother is a Department of Homeland Security liaison to the Pentagon.

The Trump administration has aggressively pursued leaks, an effort that has been enthusiastically embraced by Hegseth at the Pentagon.

Pentagon spokesperson Sean Parnell said, without evidence, that the media was "enthusiastically taking the grievances of disgruntled former employees as the sole sources for their article."

"The Trump-hating media continues to be obsessed with destroying anyone committed to President Trump's agenda. ... We've already achieved so much for the American warfighter, and will never back down," Parnell said in a statement on X.

White House spokesperson Anna Kelly said that "recently fired 'leakers'" are continuing to misrepresent the truth to soothe their shattered egos and undermine the president's agenda.

Democratic lawmakers said Hegseth could no longer stay in his job.

"We keep learning how Pete Hegseth put lives at risk," Senate Minority Leader Chuck Schumer said in a post to X. "But Trump is still too weak to fire him. Pete Hegseth must be fired."
