WASHINGTON (AP) — Hundreds of people are rallying in front of the White House, demanding that an Iranian opposition group once allied with Iraq's Saddam Hussein be removed from a U.S. terror list.Among those calling for President Barack Obama to act are former Pennsylvania governors Tom Ridge and Ed Rendell. Ridge, a Republican, served as the first U.S. homeland security secretary. Rendell is a Democrat who helped elect Obama.Both spoke Saturday in support of the Mujahedin-e Khalq, first placed on the U.S. list of terrorist groups in 1997. Last year a court ordered the State Department to reconsider the move.The MEK staged a series of bombings and assassinations in Iran in the 1980s and fought alongside Saddam's forces in the Iran-Iraq war. The group says it renounced violence in 2001.
