Members of the House Foreign Affairs Committee, led by the panel’s ranking Republican, Ileana Ros-Lehtinen (Fla.), asked the Governmental Accountability Office (GAO) to launch an inquiry into the World Meteorological Organization (WMO). An audit has shown that a WMO official misappropriated $3 million to finance a “money-for-votes scheme” before fleeing.

Noting that the U.S. has given more than $115 million to the agency, the Republican lawmakers say GAO should examine whether any part of the American contribution was among the misappropriated funds.

In addition, the GOP lawmakers called on the congressional watchdog to conduct a more thorough investigation of WMO — an audit of the audit, in effect — noting that a U.N. auditor looking into the situation had “reportedly been dismissed,” alleging she was prevented from fully examining the agency.
