Rep. Trey Gowdy, a former prosecutor, ticked through the contradictions in Hillary Clinton's public statements that were exposed by FBI Director James Comey's announcement earlier this week that the former secretary of state would not face criminal charges for her mishandling of classified information.

At a House Oversight Committee hearing Thursday, Gowdy asked Comey whether Clinton was accurate when she said she sent no classified information from her private email account.

"Our investigation found that there was classified information sent," Comey said.

Gowdy then asked whether any of those classified emails were marked as such.

"There were a small number of portion markings on, I think, three of the documents," Comey admitted.

The South Caroline Republican pressed Comey on whether Clinton carried one mobile device, as she has previously claimed.

"She used multiple devices during the four years of her term as secretary of state," the FBI director said.

Gowdy asked Comey whether Clinton had submitted all work-related emails.

"No, we found work-related emails, thousands that were not returned," he said.

Gowdy ended his line of questioning by saying that he had a plane to catch on Friday and would not be able to cover all the contradictions in Clinton's public statements before then.

Comey argued during the hearing that his team had found no evidence that Clinton intentionally mishandled classified intelligence.

"You and I both know that intent is really difficult to prove," Gowdy said before arguing that in a case similar to Clinton's, the circumstantial evidence available should have been enough to determine intent.
