WATCH: Ruth Bader Ginsburg Looks Into Future on Marriage Equality

Justice Ruth Bader Ginsburg warns that we shouldn't assume the Supreme Court is purposely keeping out of the argument over constitutionality of same-sex marriage bans.

In an interview with Katie Couric for Yahoo! News, the justice was asked whether her criticism of the Roe v. Wade opinion -- which she argues is so broad that it created unnecessary political repercussions -- also applies to marriage equality cases.

"That remains to be seen," said a smiling Ginsburg. "The court took the first step in DOMA. There will be other cases to come before the court, if not in the new term, then in the term after, or the one after that. Sooner or later the court will answer that question, and of course I can't predict how the court will decide an issue that may come before it."

Ginsburg explained why she although she supports the outcome of Roe v. Wade, she wishes the opinion had been more specific.

"That gave the right-to-life people a single target to move at, and for them it was a very effective target," she said. "It was nine unelected judges making a decision that they argued should be made by individual state legislatures."
