Singer Ricky Martin cites President Barack Obama's gay marriage support in endorsing his re-election.

“I'm standing with President Obama because he believes his family and mine are more alike than different,” the openly gay Martin says in a 48-second video for the Obama campaign. “He supports my right to be who I am and marry the person I love. And the right of all of us to live our lives openly.”

Martin came out gay in his 2010 autobiography Me. He is also raising twin sons Valentino and Matteo, who are 4 years old.

“As a parent, I'm especially thankful that the president is working to end bullying because no one should be afraid to walk down the street holding hands with the person they love,” says Martin.

“President Obama has earned my support,” he adds. (The video is embedded on this page. Visit our video library for more videos.)
