The M.E.K., which calls for an overthrow of the Iranian government and is considered by many Iranians to be a cult, once fought for Saddam Hussein and in the 1970s was responsible for bombings, attempted plane hijackings, and political assassinations. It was listed as a foreign terrorist organization in 1997.

If the State Department does decide to delist M.E.K., whose name means "People's Holy Warriors of Iran," it will be with the blessing of dozens of congressmen.
