A federal grand jury on Thursday added a charge against an Ohio man accused of plotting to attack the US Capitol, alleging in the new count that he was trying to help Islamic State extremists. The superseding indictment charges Christopher Lee Cornell, 21, of the Cincinnati suburbs, with attempting to provide material support
and resources, including himself as personnel, to a US-designated foreign terrorist organization. Counterterrorism experts are on alert for “lone wolf,” do-it-yourself terrorist plots inspired by the Islamic State extremist group. Concerns have heightened this week after two gunmen were shot dead while trying to attack an event in Garland, Texas, that featured cartoon images of the Prophet Muhammad.
