Pete Hegseth, President-elect Donald Trump's nominee for Secretary of Defense, faced criticism during his confirmation hearing as lawmakers raised concerns about his past controversies and lack of management experience. The top Democrat on the Senate committee accused Hegseth of lacking the 'character and composure' to lead the U.S. military. Hegseth, a former Fox News host, has been controversial for his views on diversity and women in combat roles. Despite strong support from Republicans, Hegseth's confirmation may depend on his performance before the Senate committee.
