WASHINGTON (AP) — Senators on Tuesday illustrated their paralysis over what to do with the Guantanamo Bay prison, voting down dueling bills to loosen and tighten restrictions on transferring detainees.

The result fails to significantly advance President Barack Obama’s long-standing goal of closing the facility for terror suspects, but prevents rules from being inserted into the Senate’s annual defense policy bill that would have made it even harder to try detainees in the United States or release them overseas.
