The nation is recognizing Memorial Day this weekend, an annual reminder to honor those who have served and sacrificed in our nation's armed forces. No one understands that sacrifice more than the families of fallen heroes. One mother has made it her mission to make sure the legacy of her son, Staff Sgt. Ryan Christian Knauss, is honored daily. Paula Knauss Selph says given today's political climate, Americans must "step up" to honor to service members both living and dead. #memorialday #fallensoldiers #rememberthefallen Start your day with "Morning in America," NewsNation's live three-hour national weekend morning newscast hosted by Hena Doba.
