California Democrat Rep. Katie Porter announces Senate bid, possible Feinstein primary challenge

California Rep. Katie Porter on Tuesday announced a 2024 Senate bid, setting up a potential primary challenge to fellow Democrat Sen. Dianne Feinstein.

Feinstein, who at 89 in the oldest sitting member of Congress, has not said whether she is running for reelection. 

She last year faced questions from the media – and anonymously from within her own party – about whether she still has the stamina and metal acuity to be a senator. 

"The real question is whether I’m still an effective representative for 40 million Californians," Feinstein responded in April 2022. "And the record shows that I am."

Porter said Monday: "California needs a warrior in the Senate—to stand up to special interests, fight the dangerous imbalance in our economy, and hold so-called leaders like Mitch McConnell accountable for rigging our democracy," Porter said in a tweet about her campaign launch. 

She won reelection in November 2022 by about 8,200 votes.
