It appears that former Chris Christie political operative David Wildstein is singing to a grand jury:

Bad news for Chris Christie — and very good news for the citizens of New Jersey: Esquire has learned from sources close to the investigation that David Wildstein, the former Port Authority operative who helped plan and execute the Great Fort Lee Clusterfk, is now cooperating with Paul Fishman, the federal prosecutor investigating the soon-to-be-ex-governor and his minions for criminal conduct. Fishman has also increased the number of investigators at work on the case, and has begun presenting evidence and witnesses to a grand jury in Newark.

Wildstein was forced to quit his PA job in December, before Fort Lee’s corpses bobbed to the surface. Christie, who went to high school with Wildstein and put him at the PA as “director of interstate capital projects” — a job created just for him — helped edit the media statement thanking Wildstein “for his service to the people of New Jersey and the region.”

In January, Wildstein refused to testify before a New Jersey legislative committee investigating last September’s George Washington Bridge lane closures, citing his 5th Amendment protection against self-incrimination. It was Wildstein’s cache of e-mails and texts, provided to the committee, that featured the instantly immortal exchange between Christie’s former deputy chief of staff, Bridget Kelly (“Time for some traffic problems in Fort Lee”) and Wildstein (“Got it”).

No wonder the mainstream Republicans are looking at Jeb Bush for President now.

Christie may serve out his term, but he is not going to be the Republican nominee.
