Updated 1:41 p.m. | The Senate confirmed Judge Neil Gorsuch as the next Supreme Court justice on Friday on a mostly party-line vote, 54-45. Democrats Joe Manchin III of West Virginia, Heidi Heitkamp of North Dakota and Joe Donnelly of Indiana joined all Republicans present in voting to confirm. Republican Johnny Isakson of Georgia did not vote.

Gorsuch was supported by the fewest number of senators since Justice Clarence Thomas was confirmed in 1991 on a 52-48 vote.

The 49-year-old appeals court judge from Colorado will be sworn in Monday, the court said.

Gorsuch is poised to join the Supreme Court and restore its previous conservative ideological tilt, emerging from an epic 14-month partisan battle over a vacancy that reshaped the Senate’s confirmation process for high court nominees.

He will fill the vacancy created by the death of Antonin Scalia in February 2016. His ascension fulfills President Donald Trump’s campaign promise to find a replacement in the mold of the reliably conservative yet polarizing justice.
