Glenn Greenwald: Chelsea Manning's Refusal to Testify Against WikiLeaks Will Help Save Press Freedom

Chelsea Manning has been sent back to jail after refusing to answer questions before a grand jury investigating WikiLeaks and its founder Julian Assange. Manning, a U.S. Army whistleblower, had been subpoenaed by federal prosecutors in Virginia's Eastern District to appear for questioning about her 2010 leak to WikiLeaks of hundreds of thousands of State Department and Pentagon documents about the U.S. wars in Iraq and Afghanistan. We speak with Glenn Greenwald, Pulitzer Prize-winning journalist and one of the founding editors of The Intercept.
