U.S. Supreme Court Justices Clarence Thomas and Sonia Sotomayor expressed concern Saturday about the lack of diverse legal and life experience among those who sit on the country's highest court.

Both are Yale University alumni and Thomas noted that all nine Supreme Court justices attended either Yale or Harvard University. He said everyone should be concerned that the nation's highest court has "such a strong Northeastern orientation."

Thomas, Sotomayor and Justice Samuel Alito, also a Yale alumnus, shared the stage Saturday when they were honored at the Connecticut school's alumni weekend. They were awarded the Yale Law School Association Award of Merit at the event. The six other Supreme Court justices all attended Harvard's law school.

"I do think we should be concerned that virtually all of us are from two law schools," Thomas said to an audience of Yale alumni and students. "I'm sure Harvard and Yale are happy, but I think we should be concerned about that. I think we should also be concerned that we have such a strong Northeastern orientation ... But I couldn't say that somebody who's a colleague of mine shouldn't be there."
