Rep. Barbara Lee has told her fellow lawmakers she’s running for Senate in California, according to two sources familiar with the situation.

She informed her colleagues in a closed-door Congressional Black Caucus meeting on Wednesday.

Asked later Wednesday about her plans, Lee said in a brief interview she’d officially announce “when it’s appropriate.”

“Right now, in respect to [Sen.] Dianne Feinstein and the floods and what I’m doing, I’m doing my work. And we’ll let them know when I intend to go to the next step. But now’s the time not to talk about that,” she said.

Lee declined to say whether she’d run against 89-year-old Feinstein if the California senator chose to run again rather than retire.

« I’m not really doing anything except letting colleagues know that there’ll be a time to talk about the Senate race, » she said.

Lee’s decision to run comes a day after Rep. Katie Porter (D-Calif.) also announced a bid for the seat currently held by Feinstein (D-Calif.). Feinstein’s future has been the subject of much speculation by Democrats in recent months, though she’s remained publicly noncommittal on her plans. It represents a safe Democratic seat for whoever can muscle through a likely crowded primary.

Lee spoke to Feinstein and California Gov. Gavin Newsom last month about her plans, according to a person familiar with the situation. Feinstein told Lee she would make a decision “soon” but understood Lee would need to plan her own bid.

A former leader of the Progressive Caucus, Lee is known as a longtime leader in California politics. Rep. Adam Schiff (D-Calif.) has also signaled his interest in running, though he hasn’t officially announced. Schiff’s camp had knocked Porter for announcing amid historic storms and flooding in California, and Schiff used his email fundraising list to raise money for storm relief.

Lee was widely seen as leading the list of potential Feinstein replacements if she were to retire early and Gov. Gavin Newsom were to choose a successor, though there’s no indication Feinstein would do so. The governor vetted Lee when then-Sen. Kamala Harris departed for the vice presidency, and he publicly committed to choosing a Black woman if he had the chance to make another appointment.

While she lacks the fundraising might of Porter and Schiff, Lee is a revered figure in the Oakland-anchored district she has represented for decades. Her deep Bay Area roots could be an asset given that both Porter and Schiff represent southern California districts.
