The Russian government arrested and imprisoned former U.S. marine, Paul Whelan, on the charge of espionage. Former U.S. intelligence officials believe the charge is in retaliation for the U.S. arrest of Russian national Maria Butina. She pled guilty to spying as part of the Russia investigation led by U.S. Special Prosecutor Robert Mueller. Whelan faces up to 20 years in prison. The global security head for an American auto parts supplier, Whelan was grabbed while in Moscow to attend a wedding. He received a “bad conduct” discharge from the Marines, according to his official military personnel file. Whelan served on multiple tours of duty in Iraq. To discuss the Whelan case, and give insight into Russia’s spy world is Luke Harding. He’s a foreign correspondent for The Guardian. As Moscow correspondent through 2011, Harding was interrogated in 2007 by Russia’s spy bureau (FSB) at Lefortovo prison, the same place where Whelan is currently held.
