The board of executive directors of the World Bank says there are still "a number of issues" involving the role President Paul Wolfowitz played in securing a promotion for his girlfriend.
The board issued a statement Friday saying it had agreed on a process to deal with the controversy "urgently, effectively and in an orderly manner."
The 24-member board met late Thursday to discuss recent revelations that Wolfowitz was instrumental in securing a sizable pay raise and a new job for Shaha Riza when he took over the bank in 2005.
Critics have accused Wolfowitz of hypocrisy because he has been pressing the bank to crack down on corruption and cronyism. He has apologized for what he called a mistake, but says he has no intention of resigning.
The White House has consistently voiced support for Wolfowitz.
The board says it is discussing issues involving a possible conflict of interest and violation of staff rules.
