House lawmakers have taken legal action against the Biden administration and subpoenaed Homeland Security Secretary Alejandro Mayorkas for information on national security and terrorism threats at the border.

House Homeland Security Chairman Mark Green (R-TN) announced Friday afternoon that the committee had sent a subpoena to Mayorkas following the panel’s “more than a year” of “stonewalling” lawmakers requests for records on illegal immigrants arrested at the U.S.-Mexico border who were on the FBI terrorist watch list.
