The AP reports:

Retired Justice Sandra Day O’Connor has officiated at the wedding of a gay couple at the Supreme Court, at least the second such ceremony at the court since its June decision that expanded federal recognition of same-sex marriage.

Court spokeswoman Kathy Arberg says O’Connor presided over the private ceremony Tuesday in the court’s lawyers’ lounge for Jeffrey Trammell and Stuart Serkin of Washington.

Justice Ruth Bader Ginsburg officiated at a weekend ceremony at the court in which two New Yorkers, including a former Ginsburg student at Columbia Law School, were married. Ginsburg has officiated at three same-sex weddings.

In June, the court struck down part of a federal law that denied a range of federal benefits to gay couples who were married in states that allow same-sex unions.
