WASHINGTON — President Donald Trump surprised Washington on Wednesday with his choice to replace James Comey a day ahead of the ousted FBI director's blockbuster congressional testimony, tapping a white-collar defense lawyer with strong law enforcement background. Senate Republicans and some Democrats praised the nomination.In an early morning two-sentence tweet, Trump said he intended to nominate Christopher Wray, a high-ranking official in George W. Bush's Justice Department who represented New Jersey Gov. Chris Christie in the Bridgegate scandal.Trump, in a statement later Wednesday, called Wray "an impeccably qualified individual.""I know that he will again serve his country as a fierce guardian of the law and model of integrity once the Senate confirms him to lead the FBI," Trump said.While the choice captured headlines early in the day, it was quickly overwhelmed by the advance release of Comey's riveting testimony, in which he said Trump sought his loyalty at a January dinner.
