Around 3,900 additional pages from Hillary Clinton's private emails have been released by the U.S. State Department.

In March 2015, it was reported that unlike former cabinet secretaries, the Democratic presidential candidate had established a private email server for her and two senior aides that ran from the basement of her Chappaqua home in New York, according to ABC News. Clinton used that private email domain to conduct official business during her term as secretary of state.

During the past 10 months, the State Department reviewed and published the majority of the 52,455 emails that Clinton yielded early in 2015, the news outlet wrote. The decision was made under a federal court order in connection with a public records lawsuit. Aside from Clinton, documents were also requested from previous secretaries due to government archiving regulations.

More Controversy

When news of her odd communications set-up first got out, Clinton pushed for the emails' publication to assure the public that she has nothing to hide, CNN reported. She also apologized for having a private email server in an interview with ABC News.

However, despite her wish to make all the emails public, the process was hindered by the fact that more than a thousand of her emails had to be redacted for having classified material, ABC News added. A total of 22 emails, which were labeled top secret, are also being withheld from the public for containing the government's most sensitive information.

Clinton's campaign pushed for the emails' release back then, accusing the intelligence community and Republican lawmakers of colluding against her to stain her presidential candidacy, the news outlet noted.

According to the State Department, the recently released emails have not been upgraded to "top secret," but two emails had to be withheld, ABC News further reported. One email was a correspondence with President Barack Obama while the other was an unclassified email that is being withheld due to a law enforcement agency's request.

ABC News learned that Clinton kept her replies short in the majority of the emails. She was also usually on the receiving end of the messages.

Criticisms Fired

Clinton also permanently deleted 30,000 pages of email that she and her lawyers consider as personal and not related to her work, ABC News further reported. This move didn't go unnoticed by Clinton's critics. Voters and political rivals have also expressed doubts over the Democratic nominee's honesty.

Clinton's server is being investigated by the FBI regarding the possibility of the mishandling of sensitive information, the news outlet added. It's vague whether the Justice Department will charge her, but the possibility of an indictment looms over her campaign.
