LOS ANGELES  — The political jockeying for the California Senate seat on the 2024 ballot is well underway, even as Democratic Sen. Dianne Feinstein has yet to say whether she'll run again.

The latest to jump into the race is Democratic Rep. Adam Schiff, who rose to national prominence as the lead prosecutor in President Donald Trump’s first impeachment trial. Schiff is joining what's expected to be a crowded field that already includes another member of the state's congressional delegation, Rep. Katie Porter. Feinstein, who joined the Senate in 1992, told reporters this week that she'll make a decision about 2024 in the “next couple of months.” In recent years, questions have arisen about her cognitive health and memory.
