Records show that President Donald Trump's pick to run the FBI represented New Jersey Gov. Chris Christie for nearly a year before a mandatory retainer agreement was signed.

WNYC-FM reports that Christopher Wray began representing Christie in September, 2014 during the George Washington Bridge lane-closing investigation. The formal agreement wasn't approved until August 2015.

A spokesman for the state attorney general's office said it had no comment. Wray didn't immediately respond to a request seeking comment.

Wray's firm, Atlanta-based King & Spalding, has been paid $2.1 million since Christie hired him in 2014.

Wray held the governor's cellphone that contained about a dozen text messages that he exchanged with a former staffer during a legislative hearing.
