Barbara Bush, daughter of former President George Bush, has recorded a PSA urging New Yorkers to support gay marriage.

“New York is about fairness and equality and everyone should have the right to marry the person that they love,” Bush says in the 22-second video.  (The video is embedded in the right panel of this page.)

Barbara joins her mother Laura Bush in speaking out in favor of gay marriage.

In an interview recorded in May, Laura spoke to CNN's Larry King on the issue.

“There are a lot of people who have trouble coming to terms with that because they see marriage as traditionally between a man and a woman,” she told King. “But I also know that, you know, when couples are committed to each other, that they ought to have, I think, the same sort of rights that everyone has.”

When asked, “You think [legalization of gay marriage] is coming?” Bush replied, “Yeah, that will come, I think.”

Last week, Robert F. Kennedy Jr. recorded a similar video.

Both ads are part of an ongoing campaign that features prominent celebrities and politicians, including Hollywood couple Kevin Bacon and Kyra Sedgwick, New York city Mayor Michael Bloomberg and singer-songwriter Moby. The campaign, backed by the Human Rights Campaign (HRC), the nation's largest gay rights advocate, hopes to build momentum on the issue now, ahead of a hoped-for second attempt to legalize the institution later this year.
