With Kamala Harris back on the campaign trail as Joe Biden s running mate, California may well have an empty Senate seat to fill come November.

Biden announced Harris as his pick for vice president on Tuesday a decision that came after a drawn-out vetting process that his campaign limited to Democratic women.

If Biden and Harris win the election in November, California Gov. Gavin Newsom will choose someone to fill Harris seat in the Senate. Unless the Democratic governor opts to call a special election next year, whomever he picks will serve out the rest of Harris term until January 2023.

Already, Newsom is facing pressure to appoint a historic candidate. Harris, who ended her own presidential bid last December, is only the second Black woman to ever serve in the U.S. Senate . There has yet to be a Latinx senator from California, even though the Latinx community makes up roughly 40% of the states population .

Rep. Karen Bass, the Los Angeles area congresswoman who chairs the Congressional Black Caucus and was also in consideration for Bidens vice president pick, has already been floated as a possible choice for the Senate seat.
