Paul Wolfowitz testified before the panel of World Bank directors today as part of the continuing investigation of his conduct in the Shaha Riza controversy and amid increasing pressure from the international community for his resignation. Oxfam International, the first “top-tier non-governmental†organization to support the resignation campaign, joined the call for Wolfowitz’s ousting in a statement to the Financial Times on Sunday, asserting that the World Bank cannot fulfill its obligation to the poor when it has been “deeply compromised†by this ethical dispute.  Wolfowitz, who was “combative†and “defiant†during his testimony according to some reports, said today, “I will not resign in the face of a plainly bogus charge of conflict of interest†and referred to the call for his resignation as a “smear campaign.”
