The Justice Department granted immunity to the former State Department staffer who set up the former secretary of state's private server and accounts.
Clinton spokesman Brian Fallon said the campaign was "pleased" that Pagliano was speaking with investigators.
In early 2009, Clinton reportedly paid Bryan Pagliano, the IT director, $5,000 to divert all of her emails to a new private server.
Clinton has remained adamant that the emails did not contain classified information at the time that they were sent and received.
According to McClatchy, as many of 1,730 Clinton emails are deemed to have contained "classified" material. When it emerged past year that she had used a private server and non-official address for all her email while in her former post as secretary of state, her Republican rivals cried foul.
Did Pagliano get immunity because he has information harmful to Clinton and/or others, or is the DOJ simply trying to make its investigation as complete as possible? That's a label Clinton and her staff have attempted to avoid as they navigate the political minefield and try to reassure voters that the likely frontrunner to become the Democratic nominee for president isn't in legal jeopardy. However, if Clinton refused to cooperate with FBI investigators, the issue could become a political flashpoint in the campaign. Yes, the FBI's case began as a security referral from the inspectors general of the State Department and the nation's intelligence agencies, who were concerned that classified information might have been stored outside a secure government network.
In August, Platte River's attorney said the server was "blank" when it was transferred to federal agents, according to The Washington Post, but did not clarify how that process took place.
"I'm sure there are people who are inclined to view things her way both within the Justice Department and outside but if he recommends, and the Bureau recommends an indictment, it's impossible to keep the lid on that".
Clinton has been under fire for using her private email server for official communications while serving as secretary of state.
Honest services fraud is generally easier to prove because the charge includes unethical conduct by public officials, Bergquist said. The question regarding Clinton's emails starts at 18:18.
The Justice Department's granting of immunity to Pagliano, diGenova pointed out, means everyone who was on Clinton's State Department staff knows now that he is talking. "Top secret" is the highest level of classification, reserved for material whose release could cause "exceptionally grave damage to the national security".
