Like many in the neoconservative movement, Perle had long been an advocate of regime change in Iraq. In 1998 Perle led an effort known as the Project for the New American Century with close neoconservative allies Wolfowitz, Woolsey, Elliott Abrams, and John Bolton. The Project culminated in a letter sent to US President Bill Clinton calling for the military overthrow of Saddam Hussein's regime. Prior to and after the 2003 invasion of Iraq, Perle held several exclusive meetings in his home where he discussed issues regarding American foreign policy on Iraq. In an effort to help fund their goals, Ahmed Chalabi an Iraqi-born businessman and founder of the Iraqi National Congress, helped Perle secure millions of dollars from the U.S. government in 1990. Chalabi was one of the key figures driving the war in Iraq and helped transmit important "information" to U.S. Congress and the public that would successfully help sell the war effort. Moreover, Perle and Chalabi also had very similar motives: they both wanted the Hussein regime deposed and Chalabi elected president. In 2004, the FBI investigated Chalabi after U.S. intelligence sources revealed that he was working as a double agent for Iran.
