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.

In a press release published by the Pentagon on Saturday after his swearing-in ceremony, Hegseth wrote, “The President gave us a clear mission: achieve Peace through Strength. We will do this in three ways—by restoring the warrior ethos, rebuilding our military, and reestablishing deterrence.”

"Pete is a disrupter" said Vice President JD Vance in explaining why he is pleased that Pete Hegseth is now the nation's secretary of Defense.

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.

Senators Lisa Murkowski, Susan Collins and Mitch McConnell voted against confirming Donald Trump’s pick for defense secretary. To Capitol insiders, their decisions weren’t surprising.

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.

Three Republicans voted with every Democrat against Trump’s controversial pick to lead the Pentagon, forcing Vance to step in and put Hegseth over the top.

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

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

The Senate voted Friday night on the confirmation of Trump's pick to lead the Department of Defense, Pete Hegseth.
