Kamala Harris has been sworn in as vice president of the United States, becoming the first woman, first Black person and first Asian American to hold the office. She is also the first graduate of a historically Black college and the first member of a Black sorority to do so.

Justice Sonia Sotomayor administered the oath. Sotomayor, the first woman of color to serve on the Supreme Court, previously administered the vice presidential oath to Biden in 2013.

Harris used two Bibles in the ceremony. The first belonged to Regina Shelton, a family friend whom Harris viewed as a surrogate mother. Harris has used this Bible before, when she took the oath of office as both California attorney general and U.S. senator. The second Bible was previously owned by the late Justice Thurgood Marshall, the first Black member of the Supreme Court and Harris’ lifelong political role model.
