Vice President Joe Biden officiated a gay wedding

In a small little milestone, Vice President Joe Biden officiated a gay wedding earlier this week.

The couple, Joe Mahshie and Brian Mosteller, are both longtime White House aides and they asked the VP to preside over their ceremony. Biden, who had never officiated before, needed to get a special temporary certification from the District of Columbia to make the marriage official. 

The intimate ceremony took place on Monday at Biden's residence at the Naval Observatory in D.C..

"Proud to marry Brian and Joe at my house," Biden tweeted along with a photo of the wedding. "Couldn't be happier, two longtime White House staffers, two great guys."

"Love is love!" added his wife Dr. Jill Biden added in a retweet.
