Christopher A. Wray, President Donald Trump's pick to succeed James Comey as FBI director, led the federal investigation of Enron and represented Gov. Chris Christie in the Bridgegate scandal.

In a tweet Wednesday morning, Trump said Wray had "impeccable credentials."

Trump tweet: I will be nominating Christopher A. Wray, a man of impeccable credentials, to be the new Director of the FBI. Details to follow.

Wray was nominated by President George W. Bush as assistant attorney general in charge of the Criminal Division, according to the Justice Department. He held that job from 2003 to 2005.

Wray, a Yale Law School graduate, served on the President's Corporate Fraud Task Force and oversaw the Enron Task Force and other major fraud investigations, according to the Washington law firm King & Spaulding, where he is a litigation partner.

The FBI says the Enron probe was the "largest and most complex white-collar investigation" in the agency's history.

Wray specializes in white collar law and internal investigations, according to the Justice Department site. He represented the New Jersey governor in the scandal surrounding the closing of lanes on the George Washington Bridge in 2013 as a way to attack political opponents. Christie was never charged but two of his allies were convicted.
