Newark Mayor Cory Booker talks to supporters during an election night victory party after winning a special election for the U.S. Senate Wednesday in Newark. Booker and Republican Steve Lonegan faced off to fill the U.S. Senate seat left vacant by the death of Sen. Frank Lautenberg.
Democrat Cory Booker will start his service as the newest U.S. senator next week.
The White House says Vice President Joe Biden will swear in Booker on Oct. 31 at noon at the U.S. Capitol. The job falls to Biden because the vice president also serves as president of the Senate.
Booker is now in his second term as mayor of Newark, N.J.
He was elected last week to complete the 15 months remaining on the term of former Sen. Frank Lautenberg, who died in June at 89.
Booker defeated conservative Republican Steven Lonegan in a special election.
Booker will become the second African-American in the Senate.
