Amanda Gorman, who at 22 is the youngest inaugural poet in American history, read “The Hill We Climb,” a poem she wrote for Biden and Harris’ swearing-in ceremony.

The National Youth Poet Laureate spoke of hope, unity, and opportunity, while also acknowledging efforts to “delay” democracy, is a stirring piece that perfectly captured the mood of the inauguration.
