Mary Cheney, the lesbian daughter of former vice president Dick Cheney, has thrown her support -- to the tune of $1,000 -- behind a congressional candidate from Ohio who believes she should not be able to adopt children.

Reports The Raw Story: "As an Ohio congressman, [Rob] Portman voted yes on banning gay adoptions in the District of Columbia in 1999. He also voted in favor of a constitutional amendment banning same-sex marriage in 2004. Portman’s opposition to same-sex marriage is particularly salient, because both of his potential Democratic challengers favor its legalization. Ohio Secretary of State Jennifer Brunner reaffirmed her backing for gay marriage in a posting at The Huffington Post in June, and a spokesman for Ohio Lt. Gov. Lee Fisher announced that he’d reversed his opposition the same month."

The website reports that Cheney made the donation back in May. Cheney has a 2-year-old son with her partner of 17 years, Heather Poe.

Earlier this year, Dick Cheney came out in support of same-sex marriage.
