Obama speech to focus on drones, Guantanamo prison

From the targeted killing of Americans overseas to the future of the military prison at Guantanamo Bay, President Barack Obama will lay out the framework and legal rationale for his administration's counterterrorism policy in a widely anticipated speech Thursday.
Administration officials tell CNN that Obama will use the National Defense University speech to continue to call on engagement with Congress on aspects of national security, more transparency in the use of drones, and a review of threats facing the United States.
