Rep. Adam Schiff announces 2024 Senate run, teeing up a high-profile primary

California Congressman Adam Schiff announced his run for Senate, entering what could be the most crowded and high-profile primary race of the 2024 cycle

Schiff announced his run in a Twitter video Thursday 

He joins Rep. Katie Porter, who announced her bid for the seat earlier this month. Reps. Ro Khanna and Barbara Lee may also be considering a run.

The seat currently held by 89-year-old Dianne Feinstein is safely Democratic, but the rest of the 2024 Senate map is expected to be difficult for 

the party – with incumbents up for reelection in swing states like Michigan, Ohio, and Arizona

Democrats are also up for reelection in solidly conservative Montana and West Virginia

Feinstein has not said whether she will run for reelection or retire next year 

She told reporters she would likely make her decision "in a couple of months," but that she had no qualms with others entering the race before then.
