Last week, two women were arrested in New York for planning to build “weapons of mass destruction against persons or property in the United States.” Inspired by Islamic State, Noelle Velentzas and Asia Siddiqui purchased bomb-making materials and prepared for attack.

Sen. Dianne Feinstein, the highest-ranking Democrat on the Senate Intelligence Committee, released a statement in response. In it, she called for vigilance in the face of terrorism and reminded us that the “threat … inside the United States endures.”
