The Administration threatened that President Bush will veto a critically needed supplemental money bill if Congress includes $822 million for the war on drugs. In a statement on the bill, the Administration said Budget Director Richard G. Darman will recommend a veto of the $3.2-billion bill if the anti-drug money and two other less controversial provisions are not rejected. The statement was released by Sen. Robert C. Byrd (D-W.Va.), chairman of the Senate Appropriations Committee. The House is expected to act this afternoon on the supplemental bill to provide money until the end of the fiscal year Sept. 30. The Senate planned to take up the bill shortly after the House.
