Of his swearing in ceremony, the Home Sweet Hollywood star tells US Weekly, “I was so proud and overwhelmed all at the same time. To take my oath and pledge allegiance beneath a giant American flag is something I will never forget. It was a very special and important day. To quote [singer] Lee Greenwood, ‘I’m proud to be an American.'”
