Carrie Underwood performs 'America the Beautiful' at Donald Trump's inauguration
Carrie Underwood performed a stirring a cappella rendition of "America the Beautiful" after the official swearing-in of President Donald Trump at his inauguration on Jan. 20. Savannah Guthrie noted during NBC News' coverage of the inauguration ceremony that Underwood spontaneously sang a cappella due to an issue with the band that was set to play with her.
