The CIA is making secret payments to multiple members of President Hamid Karzai's administration, in part to maintain sources of information in a government in which the Afghan leader is often seen as having a limited grasp of developments, according to current and former U.S. officials. The payments are long-standing in many cases and designed to help the agency maintain a deep roster of allies within the presidential palace. Some aides function as CIA informants, but others collect stipends under more informal arrangements meant to ensure their accessibility, a U.S. official said.
