Five people briefed on the requests, speaking on the condition of anonymity because they were not authorized to discuss the matter publicly, said that Daniel Coats, the current director of national intelligence, Mike Rogers, head of the National Security Agency, and Rogers's recently departed deputy, Richard Ledgett, agreed to be interviewed by Mueller's investigators as early as this week.Five leakers. Could all be from Camp Mueller. The article also says this:
It is unclear whether McCabe, Comey's successor, has informed Trump of the change in the scope of the probe.
Under the regulations, McCabe is totally out of the picture. Mueller "reports to" Rosenstein, not McCabe. Mueller is independent, but requires consultation with Rosenstein to expand the scope of his investigation.
There are rumors that WaPo is under court order surveillance to catch leakers. It would be a hoot seeing Mueller’s staff get perp walked for breaking the law here, which would end this bogus investigation and give us a big belly laugh.
