I looked it up and apparently the organization has already been delisted in 2012.
Quote:The People's Mujahedeen of Iran, more commonly known as the Mujahedeen-e-Khalq or MEK, is a controversial Iranian resistance group; it was once listed as a Foreign Terrorist Organization (FTO) by the United States for its alleged killing of U.S. personnel in Iran during the 1970s, and for its ties to former Iraqi leader Saddam Hussein. Recognizing the group's rejection of violence, the State Department delisted the MEK in late 2012 but voiced ongoing concerns about its alleged mistreatment of its members.
