Hegseth — one of Trump’s more controversial cabinet picks — was confirmed as secretary of defense in January.
Opponents argued that his prior experience – which included serving as a Fox News contributor but no government work – left him ill-equipped to run the nation’s military.
He also was facing allegations of sexual misconduct, claims of alcohol problems, accusations that several of his tattoos were coded white supremacy messages and alleged financial mismanagement of the veterans groups he oversaw.
But supporters cited his years of service in both the Army and as a veterans’ advocate in arguing for his confirmation.
They characterized the allegations against him as an organized effort by establishment Democrats to derail his appointment.
