Ahmed Wali Karzai, the brother of the Afghan president and a suspected player in the country's booming illegal opium trade, gets regular payments from the Central Intelligence Agency, and has for much of the past eight years, according to current and former American officials.
The agency pays Mr. Karzai for a variety of services, including helping to recruit an Afghan paramilitary force that operates at the C.I.A.'s direction in and around the southern city of Kandahar, Mr. Karzai's home.
