The Saturday NBC rundown included an ISIS ambush on American troops in Syria and an Arctic cold front affecting millions. The broadcast also covered a UPS plane crash in Kentucky and the escape of a Venezuelan opposition leader. The repetitive focus on Lindsey Vonn for a second consecutive day is highlighted as a distraction from more substantive news items.

NBC's Jose Diaz-Balart delivers a dramatic "Covert Moment" segment, comparing the 11-month development of the COVID vaccine to the moon landing and the effort of World War II. The hosts mock the theatrical delivery and the historical comparisons to polio and flu vaccines.
