Negotiations between the White House and a trio of powerful Republican senators snagged Wednesday over Bush administration demands that Congress reinterpret the nation's treaty obligations to allow tough CIA interrogations of terrorism suspects. Senator John Warner, chairman of the Armed Services Committee, said his panel would meet Thursday to finalize an alternative to President George W. Bush's plan to prosecute terror suspects and redefine acts that constitute war crimes. Warner said he was aware the White House may come out in opposition of his legislation. The Supreme Court ruled in June that Bush's court system established to prosecute terrorism suspects was illegal and violated the Geneva Conventions. Since then, Congress and the administration have been drafting legislation that would authorize Bush to continue with the military commissions.
