In California, progressive Congressmember Katie Porter has announced her bid for the U.S. Senate in 2024, as many expect 89-year-old Dianne Feinstein to retire at the end of her current term after serving for over three decades. A former student of Elizabeth Warren at Harvard Law, Porter has represented Orange County in the House since 2018 and is well known for her pointed, no-nonsense questioning in the House Oversight Committee. Other high-profile California Democrats who could run for the Senate seat include Congressmembers Adam Schiff, Barbara Lee and Ro Khanna.
