The U.S. Senate confirmed Pete Hegseth as Defense Secretary Friday in a dramatic late-night vote, swatting back questions about his qualifications to lead the Pentagon amid allegations of heavy drinking and aggressive behavior toward women. Rarely has a Cabinet nominee faced such wide-ranging concerns about his experience and behavior as Hegseth, particularly for such a high-profile role atop the U.S. military. But the Republican-led Senate was determined to confirm Hegseth, a former Fox News host and combat veteran who has vowed to bring a “warrior culture” to the Pentagon, rounding out President Donald Trump's top national security Cabinet officials. Vice President JD Vance was on hand to cast a tie-breaking vote, unusual in the Senate for Cabinet nominees, who typically win wider support. Hegseth himself was at the Capitol with his family. The Senate's ability to confirm Hegseth despite a grave series of allegations against him will provide a measure of Trump's political power and ability to get what he wants from the GOP-led Congress, and of the potency of the culture wars to fuel his agenda at the White House. Hegseth would lead an organization with nearly 2.1 million service members, about 780,000 civilians and a budget of $850 billion.
