FBI Director James Comey testified on Capitol Hill Thursday in front of the House Oversight Committee, where he told members he was following the investigation into Clinton's use of a private email server "very closely."
"The FBI is working on a referral given to us by inspectors general in connection with former Secretary Clinton's use of a private email server," Comey said. "As you also know about the FBI, we don't talk about our investigations while we are doing them. This is one I am following very closely and get briefed on regularly. I'm confident we have the people and resources to do it in the way I believe we do all our work, which is promptly, professionally, and independently."
At the center of the investigation is whether Clinton's use of a private email server compromised sensitive information and put national security at risk. The Washington Free Beacon first reported earlier this month the agency seized four State Department servers in a probe on how classified information was sent to the secretary of state.
Chairman Bob Goodlatte (R., Va.) asked Comey to speak in more general terms about the risk of enemies getting access to sensitive information. Comey declined to comment.
Democrats seized comments from House Majority Leader Kevin McCarthy (R., Calif.) and Rep. Richard Hannah (R., N.Y.) that insinuated Clinton's poll numbers have taken a dive because of revelations of the email server, and have called the investigation itself a partisan attack. Democrats on the committee pointed to several statements as grounds to quit the investigation altogether, despite its recent findings.
Comey said politics will play no role in his investigation because Clinton is running for president again.
"If you know my folks, you know they don't give a rip about politics."
