Federal authorities arrested Jonathan Hunter Kramer in Cranberry Township, Pennsylvania, on September 12 after he allegedly acquired a semiautomatic rifle and ammunition while preparing to conduct an attack inspired by the Islamic State.

Over the last month, American law enforcement officials separately arrested two men from California and South Carolina on terrorism charges, documenting their alleged support for the Islamic State (IS). These arrests, combined with recent guilty pleas for an election-day terrorist plot from two other individuals, indicate the jihadist group’s staying power and continued ability to attract supporters.
