Homeland Security Secretary Kristi Noem said the department is reviewing interviews with some individuals who crossed the border under former President Joe Biden to identify potential threats following the recent conflict with Iran. Noem stated that DHS is working with intelligence agencies and law enforcement to investigate and find any threats on U.S. soil, including 'dangerous individuals that came in unvetted' during the Biden administration.
Why it matters
The move comes amid heightened concerns over potential retaliation from Iran-linked operatives or sympathizers following the joint U.S.-Israel strikes on Iran. Counterterrorism agencies have been quietly monitoring suspected sleeper cells on U.S. soil, and DHS has warned of potential cyberattacks and lone wolf physical attacks as a result of the bombing in Iran.
The details
Senate Judiciary Chair Chuck Grassley, R-Iowa, questioned Noem during a DHS oversight hearing, asking about the 'millions of people' who entered the U.S. under Biden's 'open border policy' and what steps Homeland Security has taken to protect against potential Iranian sleeper cells and related terrorism. Noem replied that DHS is 'going back and we are getting some of the individuals in some of the programs that we may have concerns about looking at social media, also going through those interviews that are necessary for some of our programs that the Biden administration abused and perverted under their time there as well.'
