The impact of the border crisis under the Biden administration likely added fuel to the fire of an Iranian sleeper cell threat domestically, according to a former top Department of Homeland Security (DHS) official who briefly led Immigration and Customs Enforcement (ICE).

Following the strike on Iranian nuclear sites by the U.S. on Saturday, DHS issued a National Terrorism Advisory System Bulletin warning about the risk of domestic terrorism from Iranian-backed or inspired perpetrators.

"Definitely," former acting ICE director and Fox News contributor Jonathan Fahey said when asked if the Biden border crisis likely made matters worse domestically.
