Republican Alaska Sen. Lisa Murkowski — who broke with her party on numerous occasions to support former President Joe Biden’s nominees — became the first Republican senator to publicly oppose Pete Hegseth’s nomination to serve as Defense secretary.

The Alaska Republican’s decision Thursday comes ahead of a crucial test vote to advance Hegseth’s nomination toward confirmation.

Pete Hegseth, President Donald Trump's nominee for Defense secretary, received a positive vote from the Senate on Jan. 23 that would clear his path to confirmation despite receiving "no" votes from Republican Senators Lisa Murkowski (Alaska) and Susan Collins (Maine).

Sen. Lisa Murkowski said Thursday she will vote against Secretary of Defense nominee Pete Hegseth, who is facing a barrage of accusations about his personal conduct, making the Alaska Republican the first in her party to oppose one of President Donald Trump’s cabinet picks.

Republicans say they are confident that Hegseth, who has been accused of alcohol and domestic abuse, will ultimately be confirmed to lead the Pentagon.

The Alaska Republican plans to vote against the confirmation of Pete Hegseth to lead the Department of Defense.
