WASHINGTON (AP) - Michigan Democratic U.S. Sens. Carl Levin and Debbie Stabenow split over a proposal to prosecute and interrogate terror suspects last week, as Congress adjourned until after Election Day.

Levin voted against a detainee bill that would create military commissions to prosecute terrorism suspects. It would prohibit abuses such as mutilation and rape but would give the president room to decide which other interrogation techniques are permissible.

Democratic opponents said the bill could set a dangerous precedent that might lead to other nations mistreating captured Americans. They also focused on language barring detainees from going to federal court to protest their detention and treatment - a right referred to as habeas corpus.

"The habeas corpus language in this bill is as legally abusive of rights guaranteed in the Constitution as the actions at Abu Ghraib, Guantanamo and secret prisons that were physically abusive of detainees," Levin said.
