Kenneth C. Davis, Jari Honora, Christopher Plamp

While many Americans consider Memorial Day to be the unofficial kickoff to summer, the holiday is about much more than barbecues or big sales. Historian Kenneth C. Davis, author of The New York Times bestselling series "Don't Know Much About," discusses the history of the solemn holiday that honors military service members who have died while serving. Pope Leo XIV made history as the first U.S.-born pontiff. It was recently revealed that he has Louisiana Creole ancestry. Jari Honora, a family historian at The Historic New Orleans Collection, made the discovery and joins "CBS Mornings Plus" for more. Every year, the USO honors notable service members from each military branch. Specialists Brandon Moore and Ethan Wards were awarded as the USO National Guards Members of the Year for their disaster response during Hurricane Helene last year. They, along with USO chief operating officer Christopher Plamp, talk to "CBS Mornings Plus" about the response.
