WASHINGTON (WUSA9) -- DC Mayor Vincent Gray presided over his first same sex marriage, the first at the John Wilson building (City Hall) .
Rob Robertson married his 14-year partner Carlos Taylor with a packed room of family, friends and gay rights leaders looking on. There were also lots of Gray administration staffers looking on. For many of them it was their first same-sex wedding.
Gray says the union was in keeping with his long track record of supporting gayrights.
It is a position he hopes will serve him well, should he launch a re-election bid amid a federal probe into corruption in his 2010 campaign.
Gray has not been accused of wrong doing but several key staffers have taken felony plea deals.
