The Senate narrowly advanced the nomination of Pete Hegseth as President Donald Trump’s defense secretary on Thursday in a 51-49 vote, moving him one step closer to confirmation despite fierce objections from Senate Democrats and mounting unease among some Republicans.

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.
