Nixon in Yorba Linda, 1950
In June 1947, Nixon supported the Taft–Hartley Act, a federal law that monitors the activities and power of labor unions, and he served on the Education and Labor Committee. In August 1947, he became one of 19 House members to serve on the Herter Committee,[56] which went to Europe to report on the need for U.S. foreign aid. Nixon was the youngest member of the committee and the only Westerner.[57] Advocacy by Herter Committee members, including Nixon, led to congressional passage of the Marshall Plan.[58]

Nixon campaigning for the Senate, 1950
In his memoirs, Nixon wrote that he joined the House Un-American Activities Committee (HUAC) "at the end of 1947". However, he was already a HUAC member in early February 1947, when he heard "Enemy Number One" Gerhard Eisler and his sister Ruth Fischer testify. On February 18, 1947, Nixon referred to Eisler's belligerence toward HUAC in his maiden speech to the House. Also by early February 1947, fellow U.S. Representative Charles J. Kersten had introduced him to Father John Francis Cronin in Baltimore.
