One of President George W. Bush's twin daughters has announced her support of gay marriage.

Barbara Bush appeared in a new video released by Human Rights Campaign, a national gay rights group.

"I'm a New Yorker for marriage equality," Bush said in the video. "New York is about fairness and equality and everyone should have the right to marry the person that they love."

A spokesman for the Human Rights Campaign said the video was produced to help promote efforts to win same-sex marriage rights in New York.

The former president was an opponent of same-sex marriage and in 2004 announced his support for a proposed constitutional amendment to outlaw the practice. But his wife, former first lady Laura Bush, has said she supports gay marriage.

Spokesman David Sherzer said the former president had no comment on his daughter's video.
