NEWARK, N.J. — Oprah Winfrey is holding a fundraiser for Democratic Newark, N.J., Mayor Cory Booker's bid for the U.S. Senate.
Tickets for Thursday's event in Jersey City range from $1,000 to $2,600. Booker's campaign says about 200 people are expected to attend.
Winfrey dubbed Booker a "rock star mayor" on her show, and the two are friends.
Facebook founder Mark Zuckerberg announced his $100 million gift to Newark's schools when he and Booker appeared on Winfrey's TV show in September 2010.
Polls show Booker is the front-runner in the race to replace the late Democratic Sen. Frank Lautenberg (LOW'-tuhn-burg), who was the oldest member of the Senate and died last month at age 89. The primary election is scheduled for Aug. 13.
