Washington DC - Defense Secretary Pete Hegseth reportedly shared information on US airstrikes on Yemen in a private Signal chat group that included his wife, brother, and personal lawyer.

The bombshell reports by New York Times and CNN marked the second time Hegseth has been accused of sharing sensitive military information on the commercial messaging app with unauthorized personnel.

Last month, The Atlantic magazine revealed that its editor-in-chief was inadvertently included in a Signal chat in which officials including Hegseth and National Security Advisor Mike Waltz discussed strikes on Yemen, which took place on March 15 and killed dozens of civilians, including children.

The revelation sparked an uproar, with President Donald Trump's administration facing a scandal over the accidental leak – though not for the bombings themselves. A Pentagon Inspector-General's investigation is ongoing.

Hegseth is facing increasing criticism from within his own camp, with three former staffers penning a statement decrying their dismissals and his own former Pentagon spokesman all but calling for him to be fired on Sunday.

The Times reported that Hegseth had shared information in the second Signal group chat on the same March 15 strikes that were discussed in the accidental leak.

The information shared "included the flight schedules for the F/A-18 Hornets targeting the Houthis in Yemen," the newspaper reported.

Unlike the accidental leak where journalist Jeffrey Goldberg was mistakenly included in the group, this group chat was reportedly created by Hegseth himself.

"It included his wife and about a dozen other people from his personal and professional inner circle in January, before his confirmation as defense secretary," the Times' reported, citing unnamed sources.

Hegseth's wife Jennifer is a journalist and former Fox News producer. The group also included his brother Phil and Tim Parlatore, both of whom serve in roles at the Pentagon.

Parlatore also continues to serve as Hegseth's personal lawyer, the Times reported.

Responding to the report, Pentagon spokesman Sean Parnell accused the New York Times of being "Trump-hating media."

"There was no classified information in any Signal chat, no matter how many ways they try to write the story," he said, without providing further specifics.

Trump largely pinned the blame for the earlier leak on Waltz, but has dismissed calls to fire top officials and insisted instead on what he called the "success" of the raids on the Yemeni rebels.

This week, three top Pentagon officials were put on leave pending investigations into unspecified leaks in the Defense Department.

Deputy chief of staff Darin Selnick, senior advisor Dan Caldwell and Colin Carroll hit back on Sunday, releasing a statement saying Pentagon officials had "slandered our character with baseless attacks."

"At this time, we still have not been told what exactly we were investigated for, if there is still an active investigation, or if there was even a real investigation of 'leaks' to begin with," they said in a joint statement posted on social media.

"While this experience has been unconscionable, we remain supportive of the Trump-Vance Administration's mission to make the Pentagon great again and achieve peace through strength."

Hours after the latest reported leak, Hegseth's former Pentagon spokesperson John Ullyot published a scathing opinion piece describing "a month of total chaos at the Pentagon."

"President Donald Trump has a strong record of holding his top officials to account. Given that, it's hard to see Defense Secretary Pete Hegseth remaining in his role for much longer," wrote Ullyot.

Democrats were quick to pounce on the latest allegations, with Senate Armed Services Committee ranking member Jack Reed calling for the Pentagon Inspector-General to include the latest allegations in its probe.

"If true, this incident is another troubling example of Secretary Hegseth's reckless disregard for the laws and protocols that every other military servicemember is required to follow," he said in a statement.
