The singer was a Biden campaign supporter.
Jennifer Lopez, the singer and actress, sang the folk song “This Land Is Your Land” and “America the Beautiful,” with a brief snippet of her hit “Let’s Get Loud,” at the inauguration of Joseph R. Biden Jr. on Wednesday. In the middle of her performance, she also recited the final words of the Pledge of Allegiance in Spanish: “one nation under God, indivisible, with liberty and justice for all.” Ms. Lopez and her fiancé, the former baseball player Alex Rodriguez, both endorsed Mr. Biden during his campaign.
