State Department officials are set to release new emails Tuesday from the 55,000 pages Hillary Clinton provided to the agency in November of last year.
The State Department was forced to begin publishing portions of that batch, which contains roughly 30,000 individual communications, through a Freedom of Information Act lawsuit filed by Vice News.
Vice sued the agency after officials stonewalled its request for all of the records submitted by Clinton and many of those created by three of her top aides: Cheryl Mills, Huma Abedin and Philippe Reines.
A lawyer for Vice told the Washington Examiner the court has ordered State to publish emails once a month on a rolling basis in order to meet its production deadline of January 29, 2016.
By that date, which will fall days before the Democratic Iowa caucuses, the State Department must complete its release of the Clinton emails online.
The same court order required the agency to produce 7 percent of the documents by the end of June. That means State officials will post roughly 3,850 pages of Clinton emails on its FOIA website Tuesday.
The House Select Committee on Benghazi discovered in March that Clinton relied on a private email address and server to conduct all her government and personal affairs, touching off a national controversy that has overshadowed the early days of Clinton’s presidential campaign.
Scrutiny of her private email use was reignited earlier this month after the select committee said a witness, Sidney Blumenthal, submitted dozens of emails that State hadn’t disclosed.
State officials admitted Thursday they were unable to locate 15 of the Blumenthal emails.
In some cases, the State Department could only locate portions of records submitted by Blumenthal.
The revelation suggests Clinton sifted through her private communications and withheld those she didn’t want the public to see. It also indicates she screened the emails closely enough to identify specific passages that might cause problems for her campaign if they were released.
“We don’t know the degree to which there may be other emails that another third party may have, in this case Mr. Blumenthal, that we may not have,” State Department spokesman John Kirby said Friday.
“We did not determine what 55,000 pages were turned over, former Secretary of State Clinton did after she went through her emails and decided what was work-related,” Kirby added.
The 296 Benghazi-related emails released by the State Department on May 22 illustrated the close working relationship Clinton enjoyed with Blumenthal, despite the fact that her former aide was banned from working at the agency.
Those records also showed Clinton’s aides were preoccupied with defending their boss’ innocence in media reports about the Benghazi attacks, some of which sought to pin the security failure on the Obama administration.
