After the invasion Chalabi was placed in charge of "de-Ba'athification"—the removal of senior office holders judged to have been close supporters of the deposed Saddam Hussein. The role fell into disuse, but in early 2010 Chalabi was accused of reviving this dormant post to eliminate his political enemies, especially Sunnis. The banning of some 500 candidates prior to the general election of 7 March 2010 at the initiative of Chalabi and his Iraqi National Congress was reported to have badly damaged previously improving relations between Shias and Sunnis.
