(CNN) - Los Angeles Mayor Antonio Villaraigosa said Thursday he was forewarned of President Barack Obama's announcement that he supports same-sex marriage.
"I did know a couple of weeks ago that something would be said soon on this issue," he said on CNN's "John King, USA."

Villaraigosa also said a vote held Tuesday in North Carolina to constitutionally ban same-sex marriage wouldn't prevent Democrats from holding their convention in the state.
Asked by King whether the party should switch cities, Villaraigosa said, "I don't think so."
The mayor, who serves as the chairman of the convention, continued: "Look, we're already far down the way in terms of planning for this convention. It's going to be the most open and accessible. North Carolina is an important state, we're going to work to win the hearts and minds of votes, of the voters there. We're going to go ahead with the convention there in September."
The Democratic National Convention is scheduled to begin September 3.
