The House Un-American Activities Committee (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 media attention to make a mockery of the proceedings: Rubin came to one session dressed as an American Revolutionary War soldier, and passed out copies of the United States Declaration of Independence to people in attendance. Then Rubin "blew giant gum bubbles while his co-witnesses taunted the committee with Nazi salutes". Rubin also attended HUAC dressed as Santa Claus and a Viet Cong soldier.
