Newark Mayor Cory Booker is not officially a candidate for U.S. Senate, but his Booker for Senate exploratory fund is raking in the Hollywood cash.

Last night Booker had a $5,000 per person fundraiser at the Beverly Hills home of producer Jerry Weintraub and Susan Elkins. Jersey guy Bruce Willis was on the host committee, as were the Capshaw-Spielbergs and Meathead.

Tonight Booker raises funds in the office of prominent San Francisco law firm Keker & Van Nest.

Next week Booker is off to Chicago for two fundraisers scheduled to overlap on Tuesday.
