Washington Examiner columnist Joe Concha said a new video released by six Democratic lawmakers urging service members to reject “illegal orders” represents an extraordinary break from long-standing norms governing the military.

Concha joined Fox News’s Hannity on Thursday to discuss the video, which features Sens. Elissa Slotkin (D-MI) and Mark Kelly (D-AZ) and Reps. Jason Crow (D-CO), Maggie Goodlander (D-NH), Chris Deluzio (D-PA), and Chrissy Houlahan (D-PA). The lawmakers, all military veterans, warn of “threats to our Constitution” and repeatedly tell military and intelligence personnel to refuse unlawful commands, though they do not specify what orders they consider illegal.
