“What happened here is actually not unusual,” said John Yoo, a senior Justice Department official under President George W. Bush.

“The Judiciary Committee will often say to the Justice Department: ‘Can you send the agents back out and find out if this is true, find out what happened with this? … The normal procedure for this would have been to send the FBI out,” Yoo added.

A former Obama administration lawyer also said the FBI would look into the matter if the White House relayed such a request.

“If the FBI was asked to do it, it would do it,” said the attorney, who asked not to be named. “It doesn’t have to be a federal crime. They’ve investigating someone’s suitability for the position. … It has nothing to do with it being a federal crime.”
