WASHINGTON -- Secretary of State Hillary Rodham Clinton is blaming an exhaustive White House vetting process for the fact that the Obama administration has not yet named a person to run the U.S. Agency for International Development. Six months into the administration's tenure without having appointed someone to the agency's top spot, Clinton told USAID employees on Monday that several people had turned down the job due to overly burdensome financial and personal disclosure requirements that she called a "nightmare," "frustrating beyond words" and "ridiculous."
