A former Chris Christie aide accused of helping orchestrate Bridgegate was “freaking out” as the New Jersey governor prepared to address the lane closures for the first time in December 2013 — and asked a staffer to delete a potentially incriminating email, according to court testimony Thursday.

Christie’s former deputy chief of staff, Bridget Anne Kelly, sounded “frantic and nervous” the night before the governor was scheduled to hold a press conference Dec. 13, 2013, about the George Washington Bridge lane closures, which prosecutors say were done to punish the mayor of Fort Lee.

“She was talking in circles. Like, I was having a hard time following some of the things she was saying,” former Christie staffer Christina Renna said of the late-night telephone call.

Renna said Kelly told her, “You know, Christina, if someone tells me something is OK, who am I to question them?”

Renna added that Kelly asked her to delete an email exchange the two of them had during the lane closures.

The next day, during Christie’s press conference — in which he said none of his staffers was involved in the sleazy plot — Renna relied on that conversation when she texted with a friend, Christie campaign manager Peter Sheridan, to say Christie had just “flat-out lied” to reporters.

“She must be sh—ing herself right now,” Renna texted Sheridan during the presser.

When Sheridan asked “who,” Renna replied: “Bridget. Are you listening?”

“He just flat-out lied about senior staff and Stepien not being involved,” she said, referring to Christie’s former deputy chief of staff, Bill Stepien.

Asked about the “flat-out lied” comment in court Thursday, Renna backtracked, calling it a “poor choice of words.”
