Defense Secretary Pete Hegseth issued a warning to employees of the Department of Defense on Sunday, just days after he was sworn in to his new office.

After a few GOP senators, including McConnell, voted against Hegseth for defense secretary, the Senate narrowly voted to confirm him.

Pete Hegseth was sworn in as defense secretary Saturday morning, declaring it an “honor of a lifetime," and he promised to put America first by bringing peace through strength.

Pete Hegseth's nomination once appeared on shaky ground amid allegations that included sexual misconduct and financial mismanagement.

Pete Hegseth has vowed to bring his “warrior” ethos to the Pentagon. Democrats had assailed him as unfit for the job, and his confirmation came down to Vice President JD Vance serving as tiebreaker.

WASHINGTON – The Senate narrowly confirmed Pete Hegseth on Friday as secretary of Defense, a win for President Donald Trump's new administration after its 44-year-old nominee fended off allegations of sexual assault, public drinking and intoxication, and abusive treatment of women.

Senators voted 51-49 to advance Hegseth's defense secretary bid, which has been mired in several controversies. Two Republicans oppose him.

A Princeton and Harvard-educated former combat veteran, Hegseth went on to make a career at Fox News, where he hosted a weekend show. Trump tapped him as the defense secretary to lead an organization with nearly 2.1 million service members, about 780,000 civilians and a budget of $850 billion.

Republican lawmakers congratulated Pete Hegseth after he was narrowly confirmed as defense secretary on Friday, with GOP senators saying they were proud to vote for him.

Pete Hegseth, confirmed by the Senate as defense secretary Friday night in a 51-50 vote, with Vice President JD Vance breaking the tie, takes over leadership of the Pentagon at a time of great turmoil around the world. Let's hope, for our nation's sake, that he's up for the job.

The Senate’s 50-50 vote for Pete Hegseth marked the second time in history that a vice president was called upon to break the tie to confirm a Cabinet official.
