Tom Kean, former Republican governor and a staple in New Jersey politics, told author Ryan Lizza he’s not sure he’d back Christie if he decides to jump into the 2016 race – a dramatic statement coming from the man who helped Christie get his start in politics…

“When Chris Christie was 14 years old, he went and knocked on this guy’s door and said, ‘I want to learn how to be in politics.’ And Tom Kean taught him how to do it,” Lizza said Sunday. “He helped him become U.S. attorney. He was the first person to endorse him when he ran for governor in 2009, probably the most important person in his political life.”

Lizza said Kean offered the statement unsolicited and said he’s got his eye on other potential 2016 GOP candidates like former Florida Gov. Jeb Bush, Wisconsin Gov. Scott Walker and Ohio Gov. John Kasich.
