As the U.S. expands military operations in Syria, we look at the Khorasan group, the shadowy militant organization the Obama administration has invoked to help justify the strikes. One month ago, no one had heard of Khorasan, but now U.S. officials say it poses an imminent threat to the United States. As the strikes on Syria began, U.S. officials said Khorasan was "nearing the execution phase" of an attack on the United States or Europe, most likely an attempt to blow up a commercial plane in flight. We are joined by Murtaza Hussain of The Intercept, whose new article with Glenn Greenwald is "The Khorasan Group: Anatomy of a Fake Terror Threat to Justify Bombing Syria."
