Newark Mayor Cory Booker announced Saturday he would run to finish the late Frank Lautenberg's term in the U.S. Senate.
Booker, a 44-year-old Democrat, has served as mayor since 2006 and is Newark's third black mayor. He is hoping to claim Lautenberg's seat, which has been filled by Attorney General Jeffrey Chiesa until a special election in October.
He made the announcement at a Saturday event in which he was endorsed by former U.S. Sen. Bill Bradley.
