Ridge spoke at a conference in support of the removal of the People's Mujahedin of Iran (MEK, also PMOI, MKO) from the United States State Department list of Foreign Terrorist Organizations. The group was listed on the State Department list from 1997 until September 2012. They were placed on the list for killing six Americans in Iran during the 1970s and attempting to attack the Iranian mission to the United Nations in 1992. Ridge, along with other former government officials and politicians Ed Rendell, R. James Woolsey, Porter Goss, Louis Freeh, Michael Mukasey, James L. Jones, Rudy Giuliani, and Howard Dean, were criticized for their involvement with the group. Some were subpoenaed during an inquiry about who was paying the prominent individuals' speaking fees. Ridge and others wrote an article for the conservative publication National Review stating their position that the group should not be Classified as a terrorist organization, raising the point that, at the time, only the United States and Iran still listed it as a terrorist group.
