Joint Terrorism Task Force
The Joint Terrorism Task Force investigated and prosecuted the case.
Assistant Attorney General for National Security Matthew G. Olsen said “The National Security Division, working with our partners, is committed to identifying and holding accountable U.S. citizens who leave this country to join and support ISIS and other foreign terrorist organizations. I want to thank the many agents, analysts, and prosecutors who are responsible for this investigation and prosecution.”
U.S. Attorney Dawn N. Ison for the Eastern District of Michigan added that “Ibraheem Musaibli traveled halfway around the world and joined a vicious, brutal, and violent terrorist organization known — and proud of — its barbaric acts of terror. Today’s verdicts highlight the dedication of this office, along with our law enforcement partners, in pursuing anyone who poses a danger to the United States—no matter where they are located.”
