Occupied in an exploratory examination of a 2014 U.S. Senate run, Newark Mayor Cory Booker this afternoon called U.S. Sen. Frank Lautenberg (D-NJ) a champion for the people of New Jersey for decades whose legacy of service will improve the lives of all American's for years to come.  

"Here in Newark, his tireless advocacy and numerous contributions have helped our city endure difficult days and are now fueling our turn toward growth, promise and endless possibility. Newarkers know, from our airport and the roads we drive on to our schools and services for our seniors, Frank Lautenberg has helped empower people and strengthen our city," Booker said. "On a personal note, Senator Lautenberg has been a strong model of leadership and service to me since before I even considered entering elected office. More recently, as mayor he has been an invaluable partner in so many of Newark's recent accomplishments and successes. I look forward to continuing to work with him for the remainder of his term in the Senate and for many years to come."

Lautenberg today confirmed an NBC News report that he would not pursue re-election in 2014.

Booker and U.S. Rep. Frank Pallone (D-6) are the early contenders for Lautenberg's seat.
