Newark Mayor Cory Booker announced his candidacy on Saturday for a U.S. Senate seat for New Jersey and will run in a Democratic primary set for August to fill the seat of the late Senator Frank Lautenberg.
"I do not run from challenges. I run towards them," Booker said at a news conference in the city where he has served as mayor since 2006.
After Lautenberg's death on Monday, Republican Governor Chris Christie called a special election to fill the remainder of the late senator's term.
Booker had previously announced his intention to seek the seat when Lautenberg's term expired in 2014.
