President Barack Obama was openly rooting for the Steelers on Sunday night, but that didn't stop him from calling Cardinals coach Ken Whisenhunt after the game. Whisenhunt said the call came shortly after he returned to his home Monday afternoon. He said Obama was "congratulating our team on the success we had had and was very impressed with the way our men had played. And that was quite special." "I was actually just walking in my front door," Whisenhunt said Tuesday. "He called my cell phone. I don't know how they got my number .... I was humbled and I was stunned."
