and defamatory and ruined her career. Later, another Conservative Party candidate called for the leader of the New Democratic Party to fire a candidate for her pro-9/11 truth views. Zijad Delic, head of the Canadian Islamic Congress, Canada's largest Muslim advocacy organization, is trying to remove 9/11 conspiracy theorists from its board, in an effort to what he describes as purifying within and totally canadianize the organization. In 2008, calls for the resignation of Richard Falk, the special rapporteur on human rights in the Palestinian territories for the United Nations, were partially based on his support investigating the validity of 9/11 conspiracy theories.
