In 2008, Barack Obama became the first African American to serve as president. In 2020, Kamala Harris became vice president, making her the first woman of color to serve in an elected role in the executive branch.

Obama’s election in 2008 was notable because he was the first African American president, and Harris’s election in 2020 was notable because she was the first woman of color to serve as vice president.
