Gavin Mario Wax (born December 1993) is an American political operative who has served as the chief of staff to Darren Beattie, the acting under secretary of state for public diplomacy and public affairs, since August 2025. Wax served as the chief of staff to Federal Communications Commission commissioner Nathan Simington from April to June 2025 and as president of the New York Young Republican Club from 2019 to 2025. In April 2025, Wax became the chief of staff to Federal Communications Commission commissioner Nathan Simington. After Simington resigned in June, Wax became the chief of staff to Darren Beattie, the acting under secretary of state for public diplomacy and public affairs, in August. Peter Giunta, the president of the New York State Young Republicans, faced criticism over a deposit for a party held at the National Women's Republican Club in December 2023; Giunta later resigned and blamed the ire of the club on his criticism of Wax. In October, Politico obtained thousands of messages from leaders of Young Republican charters. Michael Bartels, a senior advisor in the Office of the General Counsel for the Small Business Administration, claimed in a notarized affidavit that Wax had provided the messages to Politico, an assertion corroborated by Giunta.
