U.S. forces and Iraqi police Thursday raided Chalabi's Baghdad offices.
CBS' "60 Minutes" reported Chalabi gave the Iranians information that could "get Americans killed" if it were revealed. An investigation is under way to determine who gave the information to Chalabi in the first place.
Members of Chalabi's Iraqi National Congress told UPI officials turned the group's headquarters in a posh villa in the al-Mansour neighborhood "upside down." They searched every room and seized computers and documents, the sources said. Chalabi was not there at the time.
A furious Chalabi told a subsequent news conference: "I am America's best friend in Iraq. If the CPA (Coalition Provisional Authority) finds it necessary to direct an armed attack against my home, you can see the state of relations between the CPA and the Iraqi people."
The raid came couple of days after the Pentagon suspended a monthly assistance of $320,000 to Chalabi's organization.
