At a Maryland ceremony for her former law clerk and his husband, Supreme Court Justice Elena Kagan officiated a gay wedding for the very first time, the AP reports:

Kagan presided on Sunday over the wedding of former clerk Mitchell Reich and Patrick Pearsall in the Washington suburb of Chevy Chase, Maryland.

Supreme Court spokeswoman Kathy Arberg said Monday that the same-sex ceremony was the first at which Kagan officiated.

Both retired Justice Sandra Day O’Connor and current Justice Ruth Bader Ginsburg have officiated at gay weddings in the past.
