Oct. 15 (UPI) -- California Sen. Dianne Feinstein, one of the longest-serving members of the U.S. Senate, will face a Democratic challenger next year.
In an email to supporters Sunday, State Senate President Pro Tempore Kevin de León announced he will take on the longtime senator in next year's party primary. De León, 50, indicated that Feinstein has not done enough to counter the Trump administration and presented himself as one who would fight for progressive values.
