In the wake of the downfall of Senator McCarthy (who never served in the House, nor HUAC), the prestige of HUAC began a gradual decline beginning in the late 1950s. By 1959, the committee was being denounced by former President Harry S. Truman as the "most un-American thing in the country today". The committee lost considerable prestige as the 1960s progressed, increasingly becoming the target of political satirists and the defiance of a new generation of political activists. HUAC subpoenaed Jerry Rubin and Abbie Hoffman of the Yippies in 1967 and again in the aftermath of the 1968 Democratic National Convention. The Yippies used the media attention to make a mockery of the proceedings. Rubin came to one session dressed as a United States Revolutionary War soldier and passed out copies of the United States Declaration of Independence to people in attendance. Rubin then "blew giant gum bubbles while his co-witnesses taunted the committee with Nazi salutes".
