Looks like Volcker is focusing on Sevan and Sevan already started the scapegoat spin by resigning yesterday:

UNITED NATIONS, Aug 7 (Reuters) – The former head of the
United Nations oil-for-food program, Benon Sevan, was accused
on Monday by a U.N.-established panel of getting nearly
$150,000 in a bribe for an oil deal.
The panel, headed by former U.S. Federal Reserve Chairman
Paul Volcker, recommended U.N. Secretary-General Kofi Annan
waive immunity for “purposes of a criminal investigation” of
Sevan and another U.N. official, named in a separate
complaint.
