While Kelly could still be subject to military law as a retired U.S. Navy captain, the basis for any prosecution related to that video “is questionable at best,” says Saira Mohamed, professor of law at the University of California, Berkeley School of Law. “I think it’s groundless,” Mohamed says of the department’s investigation. “Senator Kelly’s statement, again, is just restating the law and the obligations of members of the military and intelligence forces; it is not advising or urging insubordination or disloyalty or mutiny or refusal of duty.”
