The Adam Walsh Child Protection and Safety Act, toughening laws designed to shield children from exploitation, represented "a huge step forward," Foley told USA TODAY in an interview just before the ceremony in July.

Foley's worst moment was, presumably, nine weeks later, when he resigned in the wake of allegations that he had sent sexually suggestive e-mails and instant messages to teenage boys who had worked as congressional pages.
