In case you needed another reason to love him: ​Joe Biden, your cool uncle, officiated the wedding of two gay staffers Monday afternoon. He was so excited, he tweeted a pic of him with the newlyweds.

The wedding was between staffers Brian Mosteller and Joe Mahshie and took place at the Naval Observatory, the Vice President's official residence. The couple specifically requested that Biden officiate, reports BuzzFeed News. It was his first time officiating a wedding so he got a temporary certification to make it legal.
