The secretary of the Department of Homeland Security, Alejandro Mayorkas, has warned that one of the top threats facing the US in the lead-up to November’s presidential election are “lone offenders” aiming to disrupt voting and other public targets.
“In the aftermath of 9/11 the most prominent terrorism-related threat facing our nation was that of sophisticated foreign terrorist networks,” Mayorkas said in a keynote speech at a closed-door conference, hosted by the Soufan Center in New York.
