Joe Biden officiated his first wedding Monday night, marrying two White House staffers in an intimate ceremony at his home.
The vice president took to Twitter to share his heartfelt congratulations, writing, "Proud to marry Brian and Joe at my house. Couldn't be happier, two longtime White House staffers, two great guys."
Biden officiated the wedding (as requested by the pair) under a temporary certificate from the District of Columbia.
There's been no lack of support for the nuptials on social media. The vice president's message has been re-tweeted nearly 30,000 times, with "likes" on the tweet nearing 100,000.
Biden's wife, Dr. Jill Biden, also expressed her support for the pair, tweeting, "Love is love!" late Monday night.
Brian Mosteller, one half of the happy couple, is the special assistant to the president and director of Oval Office Operations. Mosteller's new husband Joe Mahshie serves as the first lady's trip coordinator, and is involved in her office's day-to-day operations.
The pair tied the knot in northwest Washington at the U.S. Naval Observatory, the Bidens' current residency.
