The claim that Pete Hegseth is the United States Defense Secretary is accurate.

Reasoning:

• Pete Hegseth was nominated by President-elect Donald Trump on November 12, 2024, to serve as Secretary of Defense for Trump's second term¹².
• The Senate held a confirmation hearing on January 14, 2025, and the Senate Armed Services Committee reported his nomination favorably²¹.
• Hegseth was confirmed by the Senate on January 24, 2025, in a narrow 51-50 vote, with Vice President J.D. Vance casting the tie-breaking vote²³⁴¹.
• He has been serving as Secretary of Defense since his confirmation and has already implemented several significant policy changes within the Department of Defense⁵.
