U.S. Defense Secretary Pete Hegseth, a former Fox News host, is facing intense scrutiny less than 90 days into his tenure, after a series of internal shakeups and leaks plunged the Pentagon into chaos. Hegseth is accused of sending classified military strike plans via Signal and personal text messages to his wife, brother, and attorney, prompting backlash from within his own ranks.
Following a leak investigation initiated on March 21 by his chief of staff, several key aides—including Dan Caldwell and Darin Selnick—were abruptly dismissed. Critics argue these firings have triggered instability across the Department of Defense, leaving Hegseth without his closest advisors. Former Pentagon spokesperson John Ullyot described the department as being in “total chaos” and urged President Donald Trump to replace Hegseth.
Despite mounting controversy, Trump has voiced strong support, stating Hegseth is “doing a great job” by removing entrenched officials who oppose his agenda. Hegseth has acted swiftly to implement Trump's national security goals, including the removal of diversity initiatives he labels as discriminatory.
The Pentagon’s leadership vacuum has raised concerns among defense officials, with one warning that the institution's ability to function under minimal guidance is deteriorating. Hegseth has also drawn criticism for prioritizing issues that resonate on social media over clear communication of defense policy.
His narrow Senate confirmation is now under renewed scrutiny, as Republican Senator Roger Wicker has requested an investigation into Hegseth’s use of encrypted apps following the accidental leak of strike plans in a Signal chat with a journalist.
Democrats are calling for his resignation, with Senator Elissa Slotkin accusing Hegseth of undermining military stability. The White House, however, remains reluctant to distance itself, fearing political backlash ahead of upcoming elections.
