McCain made his remarks on WPHT-AM radio in Philadelphia, during an interview in support for fellow Sen. Patrick Toomey, R-Pa.: "I promise you that we will be united against any Supreme Court nominee that Hillary Clinton, if she were president, would put up," he said. "I promise you. This is where we need the majority, and Pat Toomey is probably as articulate and effective on the floor of the Senate as anyone I have encountered."
