The officials say these interviews were planned well in advance, based on what has long been known about their use of the private e-mail server.

As for where the investigation stands, these officials say it is a long way from over.

FBI Director James Comey himself said recently that there's no deadline for finishing it. Asked if the Democratic National Convention would be such a deadline, he said no.

No conclusions have been reached about whether any laws were violated in setting up or using the system, the officials say.
