The source went on to suggest the interview may take place at her Washington, D.C. home...
...Hundreds of now-classified documents — some of them “Top Secret” — were sent and received through Clinton’s private server, which she housed at her New York residence during her tenure at the State Department.
...FBI investigators have already interviewed several Clinton aides, including her former chief of staff Cheryl Mills and her deputy chief of staff, Huma Abedin. Investigators have also interviewed Bryan Pagliano, the former State Department information technology specialist who maintained Clinton’s server. The Justice Department gave Pagliano limited immunity in exchange for his cooperation in the probe.
According to Ross, prior interviews during the investigation have been conducted by FBI agents, attorneys with the DOJ's National Security Division, and prosecutors from the U.S. Attorney's office in Alexandria, Virginia.
