Meet the Press moderator Kristen Welker joins Sunday TODAY's Willie Geist to discuss why the Democratic party is changing its primary calendar for the 2028 presidential election and break down who some of the early frontrunners are. Ukraine launched one of its largest aerial attacks of the four-year war with Russia, killing at least six people. Ukrainian President Volodymyr Zelenskyy says his military sent hundreds of drones into Russia, most of them toward the capital of Moscow. Police have arrested a suspect in connection with Saturday's mass shooting at Virginia State University just days before classes begin. Authorities say they found 19-year-old Camron Harris hiding in a dorm room closet, hours after they say he shot five people, critically wounding one of them. President Donald Trump's new executive order cuts the number of vaccines recommended for all children from 18 to 11. The administration cites rising autism rates for the change, though rigorous studies over decades have shown no link between vaccines and autism. NBC's medical contributor Dr. John Torres reports in this week's Sunday Focus on what families should know about vaccines as students head back to school. In this week's Sunday Sitdown, Tracee Ellis Ross joins Willie Geist in New York City to visit the building where she spent her childhood and talks about the new season of her Emmy-nominated show ‘Solo Traveling with Tracee Ellis Ross' and her Broadway debut with her one woman show "Every Beautiful Thing." She also shares details about growing as the daughter of music icon Diana Ross.
