In Washington, D.C., Neil Gorsuch is being sworn in as a Supreme Court justice today. Chief Justice John Roberts will administer the oath. On Friday, Gorsuch was confirmed by the Senate in a 54-45 vote, after Republican lawmakers invoked the so-called “nuclear option”—changing the Senate’s rules in order to allow Gorsuch to be confirmed by a simple majority.

Gorsuch has a long history of ruling against workers in cases involving federal race, sex, age, disability and political discrimination and retaliation claims. His confirmation was opposed by Democratic lawmakers, including Senate Minority Leader Chuck Schumer.

Sen. Chuck Schumer: “I hope Judge Gorsuch has listened to our debate here in the Senate, particularly about our concerns about the Supreme Court increasingly drifting towards becoming a more pro-corporate court that favors employers, corporations and special interests over working America.”

Neil Gorsuch will fill the seat left vacant more than a year ago after Justice Antonin Scalia died in February 2016. Senate Republicans refused to consider President Obama’s Supreme Court nomination of Merrick Garland. Gorsuch’s swearing-in today will end the longest Supreme Court vacancy since 1862.
