Annette Lantos, one of the people rescued by Wallenberg, began campaigning in the United States to get the Soviet Union to give answers regarding the disappearance, with her first attempt being in the late 1970s with her establishment of the International Free Wallenberg committee. She later tried to enlist US President Jimmy Carter to look for more information by sending in a postcard to the "Ask President Carter" radio show and by working with Simon Wiesenthal and Jack Anderson to tell Wallenberg's story through a "Washington Post" column. Noticing these efforts and angry about Sweden not going far enough in their efforts to find Wallenberg, Nina Lagergren, Wallenberg's half-sister, traveled to the United States to campaign with Lantos. The efforts of Lantos and Lagergren eventually led to the creation of the Free Wallenberg Committee in Congress, led by Senator Patrick Moynihan, whose goal was to determine what happened to Wallenberg. Lantos' husband and fellow Holocaust survivor, Tom, later continued the congressional push for answers regarding Wallenberg after being elected to the House of Representatives in 1980.
