 A bipartisan legal review by Laurence Tribe and Theodore Olson, as well as a unanimous but nonbinding Senate resolution, indicate that McCain does indeed fulfill the requirement.However, University of Arizona constitutional law professor Gabriel J. Chin argues both that the Tribe-Olson opinion is unsound under current law and that McCain was actually granted citizenship by a law which was passed eleven months after McCain's birth, disqualifying him under the Constitution from natural-born citizenship and the Presidency.Commenting on the Chin paper, Temple University law and citizenship expert Peter Spiro said, "No court will get close to it, and everyone else is on board, so there's a constitutional consensus, the merits of arguments such as this one aside."
