There is a vacancy in the office of United States Senator from New Jersey for the first time since April 12, 1982, when Nicholas Brady was appointed to fill the seat of Harrison Williams, who had resigned on March 11, 1982. Frank Lautenberg becomes the senior Senator from New Jersey for the second time. He was the senior Senator from January 4, 1997 until January 4, 2001. The last New Jersey Senator to have two separate tenures as the senior Senator was W. Warren Barbour. Barbour was appointed to the Senate in 1931, became senior Senator in 1935, and lost his seat in 1936. He won a 1938 special election to fill a vacancy in the state’s other Senate seat and became senior Senator again in 1943.
