Pete Hegseth was sworn in Saturday as the nation�s 29th secretary of defense, quickly joining President Trump�s Cabinet after a dramatic late-night vote in the Senate installed him as the Pentagon�s leader.

Hegseth took the oath from VP JD Vance with Hegseth�s wife, Jennifer Rauchet, at his side and Republican senators looking on. The ceremony came less than 12 hours after Vance broke a 50-50 tie in the Senate to narrowly seal Hegseth�s confirmation.
