Virginia Governor Terry McAuliffe, a Democrat, on Friday presided over the wedding of a lesbian couple, making him the first Virginia governor to officiate at the wedding ceremony of a gay couple.

McAuliffe married Renee Bradley, 50, and Katherine Bradley-Black, 44, at their home in Northern Virginia. The women have been together for 18 years and are raising a son, 8, and a daughter, 12.

“I was honored to be part of this important event and am pleased that marriage equality has been extended to all in VA,” he said in a tweet.

McAuliffe, who endorsed marriage equality during his campaign, continued in an email to The New York Times: “The guiding principle of my administration has been to create a commonwealth that is open and welcoming to anyone who wants to live, work and raise a family here.”

Virginia was among the states where such unions became legal on Monday after the Supreme Court refused to hear appeals in cases challenging marriage bans in five states and allowed lower court rulings to stand.
