Investigation into Hillary Clinton emails finds no deliberate mishandling of classified information

A multi-year State Department probe of emails that were sent to former Secretary of State Hillary Clinton's private computer server concluded there was no systemic or deliberate mishandling of classified information by department employees, according to a report submitted to Congress this month.

The report appears to represent a final and anticlimactic chapter in a controversy that overshadowed the 2016 presidential campaign and exposed Ms Clinton to fierce criticism that she later cited as a major factor in her loss to President Donald Trump.

In the end, State Department investigators found 38 current or former employees “culpable” of violating security procedures - none involving material that had been marked classified - in a review of roughly 33,000 emails that had been sent to or from the personal computer system Ms Clinton used.

Overall, investigators said, “there was no persuasive evidence of systemic, deliberate mishandling of classified information.” The report cited “instances of classified information being inappropriately” transmitted, but noted that the vast majority of those scrutinised “were aware of security policies and did their best to implement them.”

The release comes as Mr Trump continues to raise the Clinton email issue to attack Democrats, even as new evidence has emerged of apparent security lapses by senior officials in his own administration.

Diplomats involved in pressuring Ukraine to pursue investigations that would politically benefit Mr Trump used private phones and texting apps to trade messages about their efforts, according to records released by leaders of the House impeachment inquiry.

The State Department probe focused on internal communications that were up to nine years old.

Dozens of former state employees were brought back in for questioning in recent months after being notified that emails they had sent years ago had been retroactively classified.

The renewed activity after a long stretch in which the investigation had seemed to go dormant sparked suspicion that the Trump administration was seeking to revive an issue that had been politically advantageous to Republicans.

One former official who was questioned described it as “a way to tarnish a whole bunch of Democratic foreign policy people.”

State Department officials denied any political agenda, saying the interviews were part of the final stages of an internal inquiry that the department was under pressure to complete this month. Among those applying pressure was Republican Senator Chuck Grassley, who had sent letters to the State Department's Bureau of Diplomatic Security seeking updates.

There is no indication that any of those scrutinised will be sanctioned, but many received letters saying they were judged to have been involved in “valid” security incidents even if “not culpable” of a formal breach - an ambiguous status that some fear could complicate their abilities to return to government service.

The report does not identify those who were scrutinised, but the list included ambassadors and assistant secretaries of state responsible for US policy in the Middle East, Europe and Central Asia.

Few had sent emails directly to Ms Clinton, and instead had routed them to William Burns, who served as deputy secretary of state, or Jake Sullivan, the former director of policy planning. They then relayed many of the messages to Ms Clinton's private email, a system she said she used mainly out of convenience.

Ms Clinton's use of a private server, discovered by House Republicans as part of the probe of the deaths of US diplomats and intelligence personnel in Benghazi, Libya, triggered overlapping investigations by Congress, the State Department and the FBI.

Then-FBI Director James Comey's handling of the matter enraged Democrats. In July 2016, Mr Comey took the extraordinary step of announcing there would be no charges filed against Ms Clinton in the email probe, but accused her of being “extremely careless” in a news conference.

The bureau reopened the investigation in the final days of the 2016 race after discovering a laptop with Ms Clinton emails as part of a separate case. Most were duplicates, and, again, there were no charges, but Mr Comey's decision to notify Congress revived the issue at a moment that Ms Clinton has said was devastating to her campaign.

The State Department suspended its internal review while the FBI probe was active, before resuming work in 2017. In total, the report found 91 violations by 38 individuals, and another 497 violations “where no individual was found to bear culpability.”

The review did not encompass a separate collection of emails that Ms Clinton's lawyers withheld from the State Department and that she later destroyed, saying they were private and did not pertain to government business - a determination that was not verified by State Department officials.
