The Supreme Court declined to hear a constitutional challenge to a secretive government surveillance program, dealing a setback to privacy groups including the American Civil Liberties Union ahead of a looming debate in Congress over whether to renew the law that authorizes the intelligence tool.
In a brief order issued on Tuesday, the high court said it wouldn’t hear arguments challenging the legality of the National Security Agency program known as “Upstream,” in which the intelligence agency collects and monitors internet communications without obtaining search warrants. Classified details about the program were among those exposed a decade ago by former intelligence contractor Edward Snowden, who has been charged with theft of government property and violating espionage laws and lives in Russia.
