The news comes the same week that Newark Mayor Cory Booker has filed papers allowing him to raise money for a U.S. Senate run in New Jersey. News 4 s Brian Thompson spoke exclusively with Mayor Booker about that decision.
Lautenberg also did not say why he decided to retire when his term ends in 2015. He joked at least twice about possibly staying on. "Too late to change my mind?" he asked with a smile.
Asked after his speech who he would like to see take his seat in the Senate, he joked: "Well I'd like to have my wife do it, but she's busy."
Asked why he decided to call it quits in 2015, he said: "Nothing. I think the time with family. My children, my daughters, my grandchildren live all over the country and I want to spend more time with them."
