WASHINGTON — President Hamid Karzai of Afghanistan may still be getting his monthly cash deliveries from the C.I.A.
But now, until the Obama administration explains the rationale behind the payments, the Afghan government will have to go without $75 million in American aid.
Senator Bob Corker of Tennessee, the ranking Republican on the Foreign Relations Committee, announced Monday that he was putting a hold on the aid until the White House offered “sufficient assurances” that the bags of cash being delivered to Mr. Karzai by the C.I.A. were not fueling the corruption that pervades the Afghan government.
