Senate Majority Leader Mitch McConnell, R-Ky., praised President Trump's decision to nominate Christopher Wray as the next FBI director and argued that he is "more than qualified" to take over the bureau.

"Christopher Wray's impressive credentials make him more than ready for the sober task of leading the FBI in fulfilling its law enforcement and national security missions, especially at a time when our country faces so many serious threats both at home and abroad," McConnell said in a statement. "This, of course, is the criteria upon which an FBI Director nominee should be judged."

"The work of an FBI Director is difficult, but I'm confident that Christopher Wray is more than qualified and quite capable of shouldering this important responsibility," McConnell added. "That is what the American people expect and what the country deserves."

McConnell's comments came hours after Trump announced that he would nominate Wray to replace Andrew McCabe, the FBI acting director, and James Comey, who Trump fired in early May. In a tweet early Wednesday, Trump said that Wray has "impeccable credentials."

"I will be nominating Christopher A. Wray, a man of impeccable credentials, to be the new Director of the FBI. Details to follow," Trump said. The nomination comes only a day before Comey is set to testify before the Senate Intelligence Committee in a highly anticipated hearing.

Many Republicans, however, said Wednesday that they didn't know much about Wray, who is a former assistant attorney general.

"I don't know the guy," said House Speaker Paul Ryan, R-Wis.

Wray is also known for representing New Jersey Gov. Chris Christie's during. the Bridgegate investigation. Christie said last week that Trump "would not be making a mistake" if he tapped Wray for the post.
