Here is a full list of the winners:

Investigative reporting
Awarded to Matt Apuzzo, Adam Goldman, Eileen Sullivan and Chris Hawley of the Associated Press for their spotlighting of the New York police department's clandestine spying program that monitored daily life in Muslim communities, resulting in congressional calls for a federal investigation, and a debate over the proper role of domestic intelligence gathering.
