WASHINGTON (AP) — President Barack Obama said he’s pulling for the Pittsburgh Steelers over the Arizona Cardinals in football’s biggest game on Sunday — and he did so with a politician’s touch. Obama said Thursday that he would root for Pittsburgh against the “long-suffering” and “great Cinderella story” Cardinals. His spokesman also said the president would watch the game with members of Congress. “I have to say, you know, I wish the Cardinals the best,” Obama said diplomatically.
