  On December 20, 2012, Booker announced that he would explore running for the U.S. Senate seat then occupied by Frank Lautenberg in the 2014 election, ending speculation that he would challenge Governor Chris Christie in the 2013 gubernatorial election. On January 11, 2013, Booker filed papers to form a campaign committee without announcing whether he would run. About a month later, Lautenberg—then 89 years old—announced that he would not seek reelection in 2014.
  
  On June 3, Lautenberg died of viral pneumonia; five days later, Booker announced his intention to run for Lautenberg's seat in a 2013 special election. Booker announced his candidacy at two events, one in Newark and the other in Willingboro.
  
  On August 13, 2013, Booker was declared the winner of the Democratic primary, with approximately 59% of the vote. On October 16, he defeated Republican Steve Lonegan in the general election, 54.9% to 44.0%. Booker was the first African-American to be elected to the Senate since Barack Obama in 2004. The night before his victory, he visited the gravesite of Rabbi Menachem M. Schneerson, offering prayers and lighting a vigil candle in memory of his father.
  
  Booker resigned as mayor of Newark on October 30, and on October 31 was sworn in as the junior U.S. senator from New Jersey. He is the first African-American U.S. senator from New Jersey.
