Democratic lawmakers who appeared in a social media video urging U.S. troops to defy “illegal orders” say the FBI has contacted them to begin scheduling interviews. It comes a day after the Pentagon announced it is investigating Democratic Sen. Mark Kelly of Arizona over potential violations of military law. Michigan Sen. Elissa Slotkin told reporters Tuesday that Trump “is attempting to use the FBI to scare us.” The inquiries mark an extraordinary escalation for federal law enforcement and military institutions that traditionally steer clear of partisan clashes.
