Leading lawmakers have called for an immediate investigation into the Obama administration's controversial decision to release from prison five top Taliban leaders in exchange for an American prisoner that some troops have dubbed a "traitor."

Lawmakers were notified by the Obama administration of the release 72 hours after the prisoners were set free, according to new information released by the House Armed Services Committee.

It was further revealed that Defense Department, in a May 31 phone call, told HASC lawmakers "that the exchange was underway" and that the inmates would be freed.

Chairman Buck McKeon argues that a phone call does not meet the legal standard of congressional notification.
