House Majority Leader Eric Cantor's wife of 22 years, Diana Fine Cantor, supports gay marriage.

Mrs. Cantor spoke out on the issue during an interview broadcast Sunday on CBS' 60 Minutes.

Correspondent Lesley Stahl noted that Mrs. Cantor and her mother are liberal Democrats who converted to the Republican party but whose beliefs do not always line up with those of the Virginia representative.

When Stahl asked, “So, you're pro-choice,” Mrs. Cantor answered, “I am,” and nodded in the affirmative when asked, “Gay marriage?”

“What does that mean? You disagree with him?” Stahl asked.

“I do disagree,” Mrs. Cantor replied. (The video is embedded in the right panel of this page. Visit our video library for more videos.)

Gay rights blog notes that Mrs. Cantor is the latest GOP spouse to come out in favor of marriage equality.

Also in favor are Laura Bush, wife of former President George W. Bush, and Cindy McCain, wife of Arizona Senator John McCain.

After President Barack Obama instructed the Department of Justice to no longer defend the Defense of Marriage Act (DOMA), which bars federal agencies from recognizing the legal marriages of gay couples, the Republican-led House decided it would intervene to defend the law in court.
