Retired General and former NATO Supreme Allied Commander Wesley Clark tells me his advice for the President. Plus, new NBC News polling shows President Biden's approval rating inching higher and his race against Donald Trump getting tighter. NBC's Mark Murray and pollster Celinda Lake explain the story behind the numbers. All that and more on “The Sunday Show with Jonathan Capehart.”
