SACRAMENTO, Calif. — Democrat Kevin de Leon, president of the California Senate, says he will challenge U.S. Sen. Dianne Feinstein in next year’s election.

The Los Angeles Democrat announced via email Sunday that he’s ready to run on his progressive record fighting climate change and pushing for immigration reform, women’s rights and quality education.

His announcement did not mention the 84-year-old Feinstein by name.

Feinstein, who has been in the Senate since 1992, is its ranking Democrat on the Judiciary Committee and has never faced a serious electoral challenge from within her party.

She said last week that she’ll run for her fifth full term.
