From this:

EVEN with coalition forces engaged in Iraq, the State Department, the CIA and other key agencies remain hostile to the Iraqi National Congress - demonstrably the most effective, most representative and most democratic anti-Saddam Iraqi organization.
It would seem elementary common sense to work with the INC: It can speak to the Iraqi people as one Iraqi to another, give them guidance that is untarnished by the accents of Americans who have betrayed the Iraqis in the past and credibly explain the democratic goals of the coalition forces...

There's more on the INC at this page, and this post mentioned a suggestion from the Iraqi-American Council that they be allowed to present their/America's case to the Iraqis.
