Barbara Bush, the daughter of former President George W. Bush, has joined her mother and a growing number of former administration officials in publicly expressing support for same-sex marriage.

Bush, who has never commented publicly on the issue, appears in a new online PSA video for the Human Rights Campaign, a gay rights group.

“I’m Barbara Bush and I’m a New Yorker for marriage equality,” she says. “New York is about fairness and equality and everyone should have the right to marry the person that they love. Join us.”

The video, part of a series featuring high-profile New Yorkers, comes as rights advocates make a renewed push to legalize same-sex marriage in the Empire State, after the legislature blocked such a step in December 2009.
