Del Quentin Wilber writes: Federal prosecutors investigating the possible mishandling of classified materials on Hillary Clinton’s private email server have begun the process of setting up formal interviews with some of her longtime and closest aides, according to two people familiar with the probe, an indication that the inquiry is moving into its final phases.

“Legally it doesn’t matter if the emails were marked as classified or not, since government officials are obligated to recognize sensitive material and guard against its release. But legal experts noted that such labels would be helpful to prosecutors seeking to prove she knew the information was classified, a key element of the law.”

Those interviews and the final review of the case, however, could still take many weeks, all but guaranteeing that the investigation will continue to dog Clinton’s presidential campaign through most, if not all, of the remaining presidential primaries.

No dates have been set for questioning the advisors, but a federal prosecutor in recent weeks has called their lawyers to alert them that he would soon be doing so, the sources said. Prosecutors also are expected to seek an interview with Clinton herself, though the timing remains unclear.

The interviews by FBI agents and prosecutors will play a significant role in helping them better understand whether Clinton or her aides knowingly or negligently discussed classified government secrets over a non-secure email system when she served as secretary of State.

“This is clearly disruptive to the campaign. It will take her off message and coverage about important aides being questioned is not coverage you’d like to have. However, this issue is largely dismissed by Democratic primary voters and baked into the cake for the general electorate.”

The meetings also are an indication that much of the investigators’ background work – recovering deleted emails, understanding how the server operated and determining whether it was breached – is nearing completion.

“The interviews are critical to understand the volume of information they have accumulated,” said James McJunkin, former head of the FBI’s Washington field office.  “They are likely nearing the end of the investigation and the agents need to interview these people to put the information in context. They will then spend time aligning these statements with other information, emails, classified documents, etc., to determine whether there is a prosecutable case.”

“The facts of the case do not fit the law. Reasonable folks may think that federal law ought to prohibit what Hillary did, but it’s just not clear to me that it currently does.”

Many legal experts believe that Clinton faces little risk of being prosecuted for using the private email system to conduct official business when she served as secretary of State, though that decision has raised questions among some about her judgment. They noted that using a private email system was not banned at the time, and others in government had used personal email to transact official business.

The bigger question is whether she or her aides distributed classified material in email systems that fell outside of the department’s secure classified system. But even if prosecutors determine that she did, chances she will be found criminally liable are low. U.S. law makes it a crime for someone to knowingly or willfully retain classified information, handle it in a grossly negligent manner or to pass it to someone not entitled to see it.

Clinton has denied using the email account to send or receive materials marked classified. Though some emails have since been deemed to be too sensitive to release publicly, Clinton’s campaign has attributed that to overzealous intelligence officials and “over-classification run amok.”

Even so, her use of the private server, which was based at her home in New York, has become fodder for Clinton’s political foes as she campaigns to secure the Democratic nomination for president…..(read more
