WASHINGTON (AP) — President Barack Obama is pushing to overcome obstacles to closing the Guantanamo Bay prison, setting the White House on a collision course with Congress in its bid to loosen restrictions for moving out detainees.

Administration officials say a Senate defense policy bill coming up for debate within days would allow them to move out prisoners who have long been cleared for transfer overseas but are still held, in part because of a complicated Pentagon certification process. The bill would ease those restrictions and lift a ban on bringing suspected terrorist prisoners from Guantanamo to the United States for detention, trial or emergency medical treatment.
