[snip] The European Union, Canada and the United States formerly listed the MEK as a terrorist organization, but this designation has since been lifted, first by the Council of the European Union in January 26, 2009 (following what the group called a “seven-year-long legal and political battle”),[11][12][13] then by a decision by U.S. Secretary of State Hillary Clinton[9] on September 21, 2012 and lastly by a decision by the Canadian government on December 20, 2012.

Nonetheless, a large group of prominent former US government officials from both political parties has spent the last several years receiving substantial sums of cash to give speeches to the MEK, and have then become vocal, relentless advocates for the group, specifically for removing them from the terrorist list.
Last year, the Christian Science Monitor thoroughly described “these former high-ranking US officials - who represent the full political spectrum - [who] have been paid tens of thousands of dollars to speak in support of the MEK.” They include Democrats Howard Dean, Ed Rendell, Wesley Clark, Bill Richardson, and Lee Hamilton, and Republicans Rudy Giuliani, Fran Townsend, Tom Ridge, Michael Mukasey, and Andrew Card.
