Fifteen years ago this month, the U.S. invasion of Iraq began. Today we spend the hour with the war’s most famous whistleblower, Chelsea Manning, in her first live television interview. While serving as an Army intelligence analyst in Iraq, Manning leaked a trove of documents in 2010 about the Iraq War to WikiLeaks. She also leaked diplomatic cables, as well as information on Guantánamo and the U.S. War in Afghanistan. It would become the largest leak of classified data in U.S. history. Manning was caught and eventually sentenced to 35 years in prison—the longest sentence ever given to a whistleblower in the United States.
