Granholm: Next Justice Doesn't Have to Be a Judge

Michigan Gov. Jennifer Granholm, a potential candidate for the Supreme Court, thinks it's a smart idea for President Barack Obama to consider someone who isn't a judge now.

Granholm does have a law degree from Harvard, worked as a federal prosecutor in Detroit and was Michigan's attorney general.

She tells CNN's "State of the Union" that she thinks "it's a very wise move" to consider a potential nominee from outside "the judicial monastery." Granholm also mentions Janet Napolitano, a former Arizona governor who's now the homeland security secretary.

Justice John Paul Stevens is retiring at the end of the court's current term. Stevens and the eight other justices all were federal appeals court judges before joining the high court.
