"In 2011, an exiled Iranian political party called the Mujahedin e-Khalq, known as the MEK, paid Giuliani to give a speech in Washington calling on the State Department to remove the group from its list of terrorist organizations. The MEK recruited a host of other formal officials to its cause and succeeded in reversing the terrorist designation in 2012. A subsidiary of Giuliani's consulting firm, Giuliani Partners, advised Qatar's state-run oil company on security at a natural gas plant, The Wall Street Journal reported. Qatar is a U.S. ally that hosts a major American military base but once stifled an attempt to arrest Khalid Sheikh Mohammad, who went on to mastermind the Sept. 11 attacks, according to the 9/11 commission report. The same subsidiary, Giuliani Security & Safety, provided security advice to a Singapore gambling project on behalf of a partnership that included a tycoon close to the North Korean regime who is considered an organized crime figure by the U.S., according to a report in the Chicago Tribune. "I think the person involved, if it's correct, was a 1 percent owner that had no involvement with us, we never worked for, had nothing to do with," Giuliani told NBC's Tim Russert at the time."
