Sen. Norm Coleman, R-Minn., and Rep. Carl Levin, D-Mich., of the Senate governmental affairs investigations subcommittee, had sought internal U.N. information and individuals for their probe into the program.
Paul Volcker, chairman of the IIC-OFFP, Tuesday sent letters to U.N. Secretary-General Kofi Annan and the two senators spelling out the reasons he was not releasing the information.
He said the corruption charges "demand a response -- a full, unbiased, definitive disclosure of the evidence and of other findings." But, he explained, "The United Nations does not make such internal confidential information ... available to a particular member state," adding, "any other policy would appear to impair gravely decision-making and personnel loyalties."
Volcker, former chairman of the U.S. Federal Reserve, said information for his probe would be released when the IIC-OFF had completed its task, barring confidentiality agreements, perhaps as early as mid-2005.
