State Department top document official John Hackett, who heads Freedom of Information Act requests for the agency, told a federal judge in a court hearing Wednesday that Reines was among several officials asked to turn over any any work-related documents in his possession.

He handed over 20 boxes last night, according to a separate State lawyer present at the hearing. The hearing involved a lawsuit filed by the Associated Press that charges the agency with failing to respond to FOIA requests.

A lawyer for Reines told POLITICO many of the documents won’t likely be classified as federal records but that he was “over-inclusive in providing material to the Department — in hard copy as the regulations call for — so that the Department could decide what to retainand what to return.”

Hackett also told the court that State couldn’t produce all of the documents requested by the AP at this time — including one related to Huma Abedin’s role as a “special government employee.” He said the agency is still awaiting work-related emails from former agency officials Abedin, Jake Sullivan and Cheryl Mills. Hackett did not say whether the documents being sought were from a personal account or State.gov account.

The Reines revelations call into question the extent to which Clinton’s aides relied on personal emails for official business, which goes against government record-keeping and transparency rules.

The 2016 Democratic presidential candidate has been criticized for exclusively using personal email while serving as the nation’s lead diplomat. Clinton’s use of a home-brewed server was unearthed after Hill Republicans opened a special investigative panel to dig into the 2012 Benghazi, Libya terrorist attack. The Benghazi panel has also uncovered instances where top aides seemed to be writing from a personal email address.

Since then, Clinton has faced questions about her treatment of classified information and her secrecy..

But the court hearing suggests such controversial practices may have extended beyond her.

Reines did not respond to an emailed request for comment. But earlier this year he took Gawker to task for publishing a story suggesting he used personal email for work purposes..

Hackett said Reines sent over the document boxes with a cover letter, suggesting they contained a hodgepodge of work related items also mixed with personal messages.

To clarify, the judge asked Hackett if Reines was “asked to produce in his personal email system, federal records… and he produced 20 boxes of emails in his personal emails. Is that” your understanding?

Hackett said it was.

A source familiar with what was produced told POLITICO the bulk of what was turned over were news clips forwarded to staff from an outside vendor, which ran between 125- and 150-pages worth of stories each day. The source said those went to both Reines’ official and personal email accounts, leading to boxes upon boxes.
