According to the Los Angeles Times, the FBI is entering what it calls the “final phases” of its investigation into Hillary Clinton’s homebrew server and the potentially felonious mishandling of classified information, both on said server and by her close personal aides. But because the FBI is on no timetable to get these interviews done, this cloud is going to continue to rain on her parade well through the rest of the primary season.

No dates have been set for questioning the advisors, but a federal prosecutor in recent weeks has called their lawyers to alert them that he would soon be doing so, the sources said. Prosecutors also are expected to seek an interview with Clinton herself, though the timing remains unclear.

The interviews by FBI agents and prosecutors will play a significant role in helping them better understand whether Clinton or her aides knowingly or negligently discussed classified government secrets over a non-secure email system when she served as secretary of State.

The meetings also are an indication that much of the investigators’ background work – recovering deleted emails, understanding how the server operated and determining whether it was breached – is nearing completion.
