Former NSA contractor Edward Snowden is shedding new light on his decision to reveal classified documents about the U.S. government's mass surveillance program. In 2013, Snowden disclosed government programs that collected Americans' emails, phone calls and internet activity in the name of national security. The U.S. government charged Snowden under the Espionage Act for his actions. A congressional report said his disclosures "caused tremendous damage to national security." In his new memoir, "Permanent Record,” Snowden tells his story in detail for the first time and speaks about his life in exile in russia. Snowden, who now identifies himself as a privacy advocate, spoke with "CBS This Morning" in an exclusive U.S. TV interview. It’s edited only for satellite delays, but not for editorial content.
