Former first lady Laura Bush will be removed from a gay marriage campaign expected to begin this weekend.

The group Respect for Marriage Coalition, which is co-chaired by the Human Rights Campaign (HRC), the nation's largest gay rights advocate, acted after Bush said she does not want to be part of its campaign.

In the ad, Bush is heard telling CNN's Larry King, “When couples are committed to each other and love each other, then they ought to have the same sort of rights that everyone has.”

Anne MacDonald, a Bush spokeswoman, told The Dallas Morning News that the former first lady “did not approve of her inclusion in this advertisement nor is she associated with the group that made the ad in any way.”

“When she became aware of the advertisement last night, we requested that the group remove her from it,” MacDonald said.

The Respect for Marriage Coalition said Thursday that it was “sorry [Bush] didn't want to be included in an ad.”

The $1 million ad campaign first unveiled on Wednesday is expected to prominently be featured on network Sunday morning news shows. Print ads will begin running next week.
