Clinton’s campaign has been hounded by criticism from Republicans about the personal server, which she used exclusively during her tenure as secretary of State.

The federal investigation is centered around the possibility that Clinton or her senior aides mishandled classified information. While the State Department has maintained that none of the emails that passed through Clinton’s server were marked as classified at the time, more than 2,000 of the roughly 30,000 emails later handed over to the department and then released to the public were marked as classified at some level.

The FBI did not respond to an inquiry about the investigation concerning Clinton’s server on Friday. It was previously reported that the FBI has conducted interviews with some of Clinton's top advisers, including Huma Abedin.
