((a)) Notwithstanding any other provision of law, none of the funds authorized to be appropriated by this or any other Act shall be used for the purpose of production of lethal binary chemical munitions unless the President certifies to Congress that the production of such munitions is essential to the national interest and submits a full report thereon to the President of the Senate and the Speaker of the House of Representatives as far in advance of the production of such munitions as is practicable.
