Christopher Wray, President Trump's nominee for FBI director, said Wednesday a private meeting between the director of the FBI and the president would be "very unusual."

"In my experience, it would be very unusual for there to be any kind of one-on-one meeting between any FBI director and any president," Wray said during his confirmation hearing before the Senate Judiciary Committee.

When asked how he would respond if President Trump asked him to meet one-on-one, Wray said he would first place a call to the deputy attorney general but acknowledged there are some instances where the director of the FBI needs to speak with the president.

"My first step would be to call Deputy Attorney General Rosenstein. There's a policy that applies to contacts between the White House and the department. It goes in both directions, and in particular, it goes to any contact with respect to a particular case," he said. "There obviously are situations where the FBI director needs to be able to communicate with the president, on national security matters, for example."

Trump formally nominated Wray to succeed former FBI Director James Comey last month.

Wray currently works in private practice, but he led the Justice Department's criminal division during former President George W. Bush's administration.

From Jan. 6 to his firing on May 9, Comey met alone with Trump on numerous occasions.

During one such meeting, Trump asked Comey to join him for dinner at the White House, an invitation Comey said he thought extended to others. But when he arrived, Trump and Comey were alone.

During the meal, Trump asked Comey to pledge his loyalty to him.

In another instance, Trump asked to speak with Comey alone following a Feb. 14 meeting at the White House that included several national security officials.

During their conversation, Trump asked Comey to end the FBI's investigation into Michael Flynn, the president's former national security adviser.

Comey said he was uncomfortable with his private interactions with Trump, and at one point told Attorney General Jeff Sessions to make sure he wasn't alone with the president again.

The former FBI director also began memorializing his conversations with Trump in a series of memos, the details of which he discussed in a hearing before the Senate Select Committee on Intelligence last month.
