The brief will be filed in support of a pair of Supreme Court cases to be argued next month that challenge a California ballot initiative banning same-sex marriage and the federal Defense of Marriage Act.

Former Vice President Cheney — whose lesbian daughter wed last year — was not on the list, nor were former Secretary of State Colin Powell or former first lady Laura Bush.
