Who should be stepping down?

I heard Norm Coleman calling for Kofi Annan to step down today over recent developments in the U.N. Iraqi oil for food scandal. Aside from the fact that the U.S. itself had a fair amount of involvement in this program (if not more than Anon himself) it’s ironic that a Republican senator would call for Annan’s resignation when there hasn’t even been an indictment yet they are willing to change their own rules to keep indicted members of their own party in leadership positions.
