The House Oversight and Government Reform Committee will send a referral to the FBI on Thursday to investigate Hillary Clinton's testimony under oath last October with respect to statements about the setup of her private email server.

FBI Director James Comey told Chairman Jason Chaffetz (R-Utah) that he did not recall reviewing Clinton's testimony to the House Benghazi Committee in which she declared to Rep. Jim Jordan (R-Ohio) that "[t]here was nothing marked classified on my e-mails, either sent or received."

"I'm aware of that being said though," Comey said.

Asked whether the FBI had investigated that and other relevant statements, Comey responded, "Not to my knowledge. I don't think there's been a referral from Congress."

"Do you need a referral from Congress to investigate her statements under oath?" Chaffetz asked, to which Comey responded, "Sure do."

With a chuckle, Chaffetz said, "You'll have one. You'll have one in the next few hours."
