WASHINGTON - President Barack Obama sought Thursday to advance the U.S. beyond the unrelenting war effort of the past dozen years, defining a narrower terror threat from smaller networks and homegrown extremists rather than the grandiose plots of Osama bin Laden's al-Qaida.

He also argued that changing threats require changes to the nation's counterterrorism policies.

Obama implored Congress to close the much-maligned Guantanamo Bay detention center in Cuba and pledged to allow greater oversight of the drone program.

DURHAM, N.C. - Duke coach Mike Krzyzewski just couldn't pass on "the ultimate honor" of representing his country again as the U.S. men's national team coach.

Krzyzewski is returning as coach through 2016, extending a run that included leading the Americans to two straight Olympic golds while helping reshape a program that needed a jolt to keep up with the growth of international basketball.

Krzyzewski, 66, took over as coach as USA Basketball began its national-team program in 2005.
