Who is Laphonza Butler, California Gov. Gavin Newsom's choice to replace Feinstein in the Senate?

California Gov. Gavin Newsom announced Sunday that he is appointing Laphonza Butler to the U.S. Senate to replace Sen. Dianne Feinstein, who died last week at the age of 90.

Butler posted on X, formerly Twitter, on Monday that she is "honored" to accept Newsom's appointment, and she said "I am ready to serve." Butler is currently the president of EMILYs List, a Democratic group dedicated to electing women who support abortion rights.

Vice President Kamala Harris plans to swear Butler in on Tuesday.
