The U.S. State Department says it does not want to pre-judge the results of U.S. and U.N. investigations into alleged fraud in Iraq's U.N.-administered oil-for-food program.

Spokesman Adam Ereli said Wednesday the United States wants the facts be aired fully and appropriate actions taken.

Earlier, U.S. Senator Norm Coleman called on U.N. Secretary-General Kofi Annan to resign, because he was in charge during what the senator called the "most extensive fraud in the history of the U. N."

Mr. Coleman heads the Senate Government Affairs subcommittee on investigations, which said last month that it had uncovered evidence of widespread irregularities in the oil-for-food program.

The United Nations is also investigating the charges.
