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.

Van Haften appeared in court in Madison on Friday for an arraignment. His attorney, federal public defender Joseph Bugni, entered a not guilty plea on his behalf.

U.S. Magistrate Judge Stephen Crocker set a status conference for May 27.
