An Iranian drone killed six U.S. service members at a tactical operations center in Kuwait on March 1, 2026, and survivors disputed the Pentagon's account, saying their unit was left dangerously exposed and "was unprepared to provide any defense for itself". Four Democratic senators including Warren launched an investigation, with Warren stating Hegseth "refused to take basic steps to protect them, and then tried to cover up his failures when service members died." The core dispute centers on whether the facility was adequately fortified and whether Hegseth's public characterization was misleading—both of which are now the subject of congressional investigation.
