Source: Clinton IT specialist revealing server details to FBI, 'devastating witness'
"Bryan Pagliano is a devastating witness and, as the webmaster, knows exactly who had access to [Clinton's] computer and devices at specific times. His importance to this case cannot be over-emphasized,"
the intelligence source said.
The source, who is not authorized to speak on the record due to the sensitivity of the ongoing investigation, said Pagliano has provided information allowing investigators to knit together the emails with other evidence, including images of Clinton on the road as secretary of state.
The cross-referencing of evidence could help investigators pinpoint potential gaps in the email record. "Don't forget all those photos with her using various devices and it is easy to track the whereabouts of her phone," the source said.
"It is still boils down to a paper case. Did you email at this time from your home or elsewhere using this device? And here is a picture of you and your aides holding the devices."
