Time to put a name with the man at the center of the Secret Service scandal. Arthur Huntington has been identified as the agent who refused to pay a prostitute in Colombia, and then sparked a sweeping investigation that's led to the discipline and firings of 12 Secret Service agents. The agent, who lives in Saverna Park, Md., is a married father of two whose wife leads Bible study in the neighborhood. In light of the scandal, the Secret Service has created new rules forbidding all foreigners but hotel staff in agents' rooms and barring them from visiting "seedy establishments."
