The Department of Homeland Security (DHS) on Nov. 30 issued a warning about a “heightened threat environment” ahead of the holiday season in the United States.
“Our homeland continues to face a heightened threat environment—as we have seen, tragically, in recent acts of targeted violence—and is driven by violent extremists seeking to further a political or social goal or act on a grievance,” DHS Secretary Alejandro Mayorkas said in a statement.
