U.S. border czar Tom Homan and former DHS secretary Chad Wolf have raised alarms about the potential infiltration of Iranian ‘sleeper cells’ into the United States, attributing this risk to Biden-era open border policies. Homan, labeling it the ‘biggest national security vulnerability,’ emphasized that thousands of foreign nationals have entered the U.S. illegally, with many being released back into the country. Wolf echoed these concerns, linking the Biden administration’s border crisis to a heightened threat from groups like Hezbollah and Hamas. The Department of Homeland Security has issued a memo warning of a ‘heightened threat environment,’ coming days after U.S. military strikes on key Iranian nuclear sites. Officials warn that the situation may lead to retaliatory actions, with the FBI and local law enforcement working to mitigate the risk.
