Tick, tick, tick! Does anyone believe that the Clinton campaign is pleased that Mr. Paliano is talking with the FBI?
1900 plus classified e-mails on a home brew, unclassified server. Someone had to physically move that material from a highly classified system to a unauthorized/unclassified system.

The Justice Department has granted immunity to a former State Department staffer, who worked on Hillary Clinton’s private email server, as part of a criminal investigation into the possible mishandling of classified information, according to a senior law enforcement official.

The official said the FBI had secured the cooperation of Bryan Pagliano, who worked on Clinton’s 2008 presidential campaign before setting up the server in her New York home in 2009.As the FBI looks to wrap up its investigation in the coming months, agents are likely to want to interview Clinton and her senior aides about the decision to use a private server, how it was set up, and whether any of the participants knew they were sending classified information in emails, current and former officials said.


"He also said the campaign is “pleased” that Pagliano, who invoked his Fifth Amendment rights before a congressional panel in September, is now cooperating with prosecutors. The campaign had encouraged Pagliano to testify before Congress."
