Captain Ed is all over this, and with good reason.
The trail of corruption regarding how Cotecna (Kojo Annan, son of Kofi, worked there) received Oil-for-Food contracts officially leads to Kofi Annan himself. Two memos by Cotecna veep Michael Wilson constitute the smoking gun.
Paul Volcker had accepted Kofi Annan's denial of any involvement in the Cotecna contract award. That denial is worthless. Kofi must go.
