WASHINGTON — The U.S. Senate confirmed House Budget Committee Chairman Tom Price (R., Ga.), President Donald Trump’s nominee to lead the Department of Health and Human Services, in a 52-47 party-line vote early Friday morning, placing him atop a sprawling agency tasked with dismantling the Affordable Care Act.

Price’s nomination served as the first major proxy fight in Congress over the fate of former President Barack Obama’s signature health law, which Republicans have vowed to repeal and replace. The 62-year-old former orthopedic surgeon has earned a reputation in Congress as a leader in pushing his party’s health-policy plans—especially an alternative to the ACA.
