A member of New Jersey Gov. Chris Christie's (R) staff who was recently subpoenaed in relation to Christie's bridge controversy has left his office, according to AP:

Christina Genovese Renna left the governor’s office Friday, the same day former Christie loyalist David Wildstein claimed to have evidence contradicting the governor’s account of a lane closing operation, apparently to create traffic chaos as a political vendetta.

Renna reported to Deputy Chief of Staff Bridget Kelly, who apparently set the lane closings in motion with an email to Wildstein.

Renna confirmed her resignation to The Associated Press through a statement Sunday from her lawyer, Henry Klingeman.

In it, Renna says she has been considering leaving since after the November election, which Christie won decisively.

Renna is among 17 people close to Christie subpoenaed by a legislative panel.

Renna is the fourth Christie aide or appointee to leave or be fired since questions about the lane closures in Fort Lee, N.J., first began in September. The others are former Christie deputy chief of staff Bridget Kelly, who was fired, and former Port Authority appointees Wildstein and Bill Baroni, who resigned.
