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.

The Senate narrowly voted to confirm embattled Pete Hegseth as secretary of the Department of Defense, in a major win for President Donald Trump and his new administration.

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 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.

Vice President JD Vance was forced to step in after Kentucky Senator Mitch McConnell broke ranks and voted against Hegseth.

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.

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.

The Senate on Friday night confirmed President Donald Trump’s nomination of Pete Hegseth, a former Fox News personality, to become the country’s next defense secretary.
