A Wisconsin man has pleaded not guilty to a federal charge that he tried to join the Islamic State terror group.
Prosecutors have charged 34-year-old Joshua Van Haften with trying to provide material assistance to a foreign terrorist group.
He was arrested at O'Hare International Airport in Chicago earlier this month. Investigators said he had flown back from Turkey after a failed bid to join the terror group in Syria. He could face up to 15 years in prison and $250,000 in fines if he's convicted.
