Mary Ann Glendon is a member of the IRD Advisory Board and the Learned Hand Professor of Law at Harvard University. According to the Boston Globe, she is "the highest-ranking female adviser in the Catholic Church". In 2004, she was appointed by Pope John Paul II to head the Pontifical Academy of Social Science which produces research upon which the Catholic Church establishes its social policy. In 1995, she headed the 22-member delegation of the Holy See to the Fourth United Nations' Women's Conference in Beijing. She has been mentioned as a possible Supreme Court justice nominee and is a member of President Bush's Council on Bioethics.

Glendon also serves on the Catholic League's Board of Advisors with three other IRD associates: Robert George, Michael Novak and George Weigel. The Catholic League purports to defend Catholics' right "to participate in American public life without defamation or discrimination." However, John M. Swomley, emeritus professor of social ethics at St. Paul School of Theology in Kansas City, Missouri, calls the Catholic League one of the "most dangerous of the far-right organizations". He wrote that while "it masquerades as a civil rights organization," the Catholic League's actual "mission is to censor or suppress any activity, language, speech, publication, or media presentation that it considers offensive to the papacy, the Vatican, or the Catholic church in America".

William A. Donohue, who has been the president of the League since 1993, appears frequently on news programs, primarily to attack gays, progressives, and Hollywood. Recently he declared on national television "there are people in Hollywood, not all of them, but there are some people who are nothing more than harlots" who "will do anything for the buck." He added that, if asked "to sodomize their own mother in a movie, they would do so, and they would do it with a smile on their face." And, "Hollywood is controlled by secular Jews who hate Christianity in general and Catholicism in particular...Hollywood likes anal sex."

Glendon remains on the advisory boards of both IRD and the Catholic League to this day.
