Answer:
To date, 10 African Americans have served in the United States Senate. In 1870 Hiram Revels of Mississippi became the first African American senator. Five years later, Blanche K. Bruce of Mississippi took the oath of office. It would be nearly another century, 1967, before Edward Brooke of Massachusetts followed in their historic footsteps. Carol Moseley Braun broke new ground in 1993, becoming the first African American woman to serve as U.S. senator. In 2005 Barack Obama of Illinois became the fifth African American to serve and third to be popularly elected. Upon Obama's resignation to become the nation's first African American president, Roland Burris was appointed to fill the vacancy, becoming the sixth African American senator and the third to occupy the same Illinois Senate seat. Tim Scott of South Carolina was appointed to fill a vacancy in 2013, becoming the first African American since Reconstruction to represent a southern state in the Senate. He won a special election in 2014 to complete the term and was elected to a full term in 2016. The appointment of Massachusetts senator William "Mo" Cowan on February 1, 2013, marked the first time that two African Americans have served simultaneously in the United States Senate. Cory Booker of New Jersey became the ninth African American senator when he won a special election to replace Senator Frank Lautenberg on October 31, 2013. Booker won election to a full term in 2014. Kamala Harris became California's first African American senator on January 3, 2017, bringing the number of African Americans serving simultaneously to three and the total number of African American senators to 10.
