As Chalabi's position of trust with the Pentagon crumbled, he found a new political position as a champion of Iraq's Shi'ites (Chalabi himself was a Shi'ite). Beginning 25 January 2004, Chalabi and his close associates promoted the claim that leaders around the world were illegally profiting from the Oil for Food program. These charges were around the same time that UN envoy Lakhdar Brahimi indicated that Chalabi would likely not be welcome in a future Iraqi government. Up until this time, Chalabi had been mentioned formally several times in connection with possible future leadership positions. Chalabi contended that documents in his possession detailed the misconduct, but he did not provide any documents or other evidence. The U.S. sharply criticized Chalabi's Oil for Food investigation as undermining the credibility of its own.
