​President Trump announced he would nominate Christopher Wray, who represented New Jersey Gov. Chris Christie during the Bridgegate scandal, as the new FBI director.​

​”​I will be nominating Christopher A. Wray, a man of impeccable credentials, to be the new Director of the FBI. Details to follow​,” the president wrote in a tweet on Wednesday.​

A former assistant attorney general who led the Justice Department’s criminal division, Wray was appointed by former President George W. Bush.

He left the Justice Department in 2005 and now works with the private law firm King and Spalding.

The post had been vacant since May 9 when the president fired then-director James Comey, who was investigating Russian involvement in the 2016 election and whether Trump campaign associates colluded with the Kremlin.

Comey is scheduled to appear before the Senate Intelligence Committee on Thursday to testify about the investigation.

Christie, a Trump supporter who led the president’s transition team, and Wray have a long relationship dating back to when the governor was a US attorney. The two collaborated on the fraud investigation into drug-maker Bristol-Myers Squibb.

Christie gave a full-throated endorsement of Wray last week.

“I have the utmost confidence in Chris. He’s an outstanding lawyer. He has absolute integrity and honesty, and I think that the president certainly would not be making a mistake if he asked Chris Wray to be FBI director,” Christie told North Jersey.com.

Before nominating Wray, Trump interviewed acting FBI Director Andrew McCabe, former top FBI official Richard McFeely and former Oklahoma Gov. Frank Keating for the post.

Former Connecticut Sen. Joe Lieberman was said to be in the running, but withdrew from consideration. Lieberman, an attorney at the law firm representing Trump in the Russia probes, said he wanted to “avoid any appearance of conflict of interest.”
