President Barack Obama and former First Lady Michelle Obama joined Stevie Wonder onstage Tuesday (October 15) at CFG Bank Arena in Baltimore for his tour stop.

Wonder encourages voters on his 10-city “Sing Your Song! As We Fix Our Nation’s Broken Heart” tour before election day.

Democratic President Barack Obama has endorsed Vice President Kamala Harris in the presidential race. He surprised Kamala Harris’ campaign staff in Pittsburgh last week.

Wonder is legendary. Before performing at the August Democratic Convention, he had won 25 Grammys and was inducted into the Rock and Roll and Songwriters Hall of Fame. He received the Presidential Medal of Freedom and helped make Martin Luther King Jr.’s birthday a federal holiday.

His hit songs include “I Just Called to Say I Love You,” “I Wish,” “Sir Duke,” “Higher Ground,” “Superstition,” and “Isn’t She Lovely.”

A concertgoer got to capture the moment, saying,”I’m at a Stevie Wonder concert, and lemme tell you… I did not expect the Obamas to walk out with him.”
