WASHINGTON–A Wisconsin man was sentenced to 10 years in federal prison and lifetime supervised release for attempting to provide material support, namely himself as personnel, to the Islamic State of Iraq and the Levant (ISIL), a designated foreign terrorist organization.

Joshua Van Haften, 36, of Madison, admitted that in 2014, he attempted to provide material support to ISIL, knowing that the organization was a designated terrorist organization that has engaged and engages in terrorism.

“With this sentence, Joshua Van Haften will be held accountable for attempting to travel overseas to join ISIL and to provide material support to the designated terrorist organization,” said Acting Assistant Attorney General Mary McCord. “The National Security Division’s highest priority is countering terrorist threats, and we will continue to work to stem the flow of foreign fighters abroad and bring to justice those who attempt to provide material support to designated foreign terrorist organizations.”

“The U.S. Attorney’s Office and the FBI, working with our state and local partners on the Joint Terrorism Task Force, will continue to work to investigate, arrest, and vigorously prosecute all extremists who choose to aid ISIL, or any other terrorist organization, and to stop them before they harm the United States or our allies,” said U.S. Attorney John Vaudreuil. “We also remain committed to working with dedicated community members to bring this cycle to an end.”

According to the government’s evidence, Van Haften traveled to Turkey in 2014 and attempted to cross into Syria. He posted online that he had taken an oath of allegiance to the leader of ISIL, and that “The only thing that matters to me is joining my brothers for the war against America [sic] liars.”

In addition to traveling to Turkey in an attempt to fight with ISIL, Van Haften tried to assist another American, Leon Davis, in joining ISIL. He attempted to meet Davis in Istanbul upon Davis’s arrival – actually waiting for Davis at a bus stop in Istanbul – and planned to travel with Davis to Syria to join and fight with ISIL.

Leon Davis, of Augusta, Georgia, was sentenced to 15 years in federal prison in July 2015, following his conviction in the Southern District of Georgia for attempting to provide material support to a designated foreign terrorist organization, namely ISIL.

Van Haften was arrested at O’Hare Airport in Chicago, Illinois in April 2015, after his arrival in custody on an international flight from Turkey. He has been held in federal custody since his arrest.
