America's largest newspapers - The Wall Street Journal, The Washington Post and The New York Times - are dedicating their pages to the Journal's Evan Gershkovich as he spends his fourth week behind bars in a Russian prison, facing trumped-up charge of espionage. The papers are running a full-page letter in their print editions, where they write: "As editors and publishers of some of America's largest news organizations, we are united in calling for his immediate release. Reporting is not a crime." His arrest is one of the latest flashpoints in a world where autocratic leaders increasingly feel free to lock up anybody who can be used as a political pawn - anyone they perceive as a threat to their rule. Christiane sat down with The Wall Street Journal's Editor-in-chief Emma Tucker to discuss what she's doing to help bring Evan home.
