"We're not seeing the organized structures with a hierarchical architecture, that's not what we're seeing in the current threat stream of domestic terrorism," Mayorkas said during a National Press Club event when asked if there are sleeper cells in the United States.
However, Mayorkas pointed out that the agency receives information from the public concerning people showing signs of radicalization and threat of violence.
The Department of Homeland Security is working to expand domestic terrorism awareness to local US communities besides airports, train stations and bus stations, Mayorkas said.
Moreover, Mayorkas said the agency has seen no information to suggest Daesh terrorists* came into the United States through the Afghan population that was evacuated out of Kabul.
*Daesh (also known as ISIS/ISIL/IS) is a terrorist organization outlawed in Russia and many other states
