James Comey. FBI Director.

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.
