Supreme Court Justice Elana Kagan over the weekend officiated for the first time at the wedding of a gay couple.

According to the AP, Kagan presided over the wedding of Mitchell Reich, a former Kagan law clerk, and Patrick Pearsall.

A New York Times wedding announcement lists Reich as a 27-year-old Justice Department lawyer and Pearsall as a 34-year-old State Department lawyer.

The couple exchanged vows at Wooden Sanctuary in the Washington suburb of Chevy Chase, Maryland. A law approved by lawmakers allowing gay couples to marry took effect on January 1, 2013 after winning approval from Maryland voters.

While it was the first such wedding for Kagan, retired Justice Sandra Day O'Connor and Justice Ruth Bader Ginsburg have previously married gay couples.

Earlier this month, Ginsburg officiated over the wedding of Danny Rubens, a former Ginsburg law clerk, and Danny Grossman in New York.
