Frank George Wisner II (born July 2, 1938) is an American businessman and former diplomat who had served as acting United States Secretary of State for a few hours following the resignation of the previous acting United States Secretary of State Arnold Kanter at noon on January 20, 1993 until the confirmation by the United States Senate and swearing in of Warren Christopher as United States Secretary of State later that day. He is the son of CIA official Frank Wisner (1909–1965). On January 31, 2011, he was sent to Egypt by President Barack Obama to negotiate a resolution to the popular protests against the regime that had swept the country. A White House spokesman said that Wisner had vast experience in the region as well as close relationships with many Egyptians in and out of government. The New York Times reports that he is a personal friend of former Egyptian president Hosni Mubarak.
