Joe Biden picked California Senator Kamala Harris as his vice presidential nominee on Tuesday.

“I have the great honor to announce that I’ve picked @KamalaHarris — a fearless fighter for the little guy, and one of the country’s finest public servants — as my running mate,” Biden tweeted.

Harris, 55, is the first Black woman to be nominated for vice president. She campaigned for the Democratic party’s presidential nomination, but dropped out before the first votes were cast. 

A lawyer, Harris served as District Attorney of San Francisco and California Attorney General before winning election to the U.S. Senate in 2016. 

Democrats are scheduled to nominate Biden/Harris next week in Milwaukee, Wisconsin. 

The general election is Nov. 3.
