Democratic Rep. Rush Holt will run in New Jersey's October 16 special election for Senate, set by Gov. Chris Christie after the death of Sen. Frank Lautenberg.
Holt, an eight-term congressman who represents central New Jersey, made his announcement via e-mail and Twitter on Thursday morning.
"I believe I am the best candidate to continue the passionate advocacy for progressive values that Sen. Lautenberg exemplified," said Holt, the only physicist serving in Congress.
The body of Lautenberg, who died Monday, aged 89, will lie in repose inside the U.S. Senate chamber on Thursday afternoon, and the World War II veteran will be buried at Arlington National Cemetery Friday.
Candidates making a bid to fill Lautenberg's seat for the remainder of his term, which ends in January 2015, must submit petitions with 1,000 signatures to the state's election division by Monday.
Newark Mayor Cory Booker, who had already declared his intention to run for the Senate in 2014, is widely expected to enter the race setting up a primary with Holt.
Christie has said he intends to appoint a temporary successor to Lautenberg by next week.
