Oil for Food: Annan Attempting to Block Investigation?

The leaders of the Senate investigations subcommittee criticized the United Nations on Tuesday for failing to provide access to its officials and documents for the panel's inquiry into the oil-for-food aid program in Iraq.

Dileep Nair, a Singaporean who supervises the United Nations' auditing office, had not been permitted to testify.

Senator Coleman, an outspoken critic of the former Iraq aid program and of Secretary General Kofi Annan, also called on Mr. Annan to lift diplomatic immunity from Benon V. Sevan, who ran the program.
