Former Secretary of State requested her communications to be made public following criticism over private email address.
Hundreds of emails by former top US diplomat Hillary Clinton were released by the State Department, seeking to quell a lingering political row about a deadly 2012 attack on a US mission in Libya.
The emails have stoked fresh controversy since Clinton – who is now running for president – admitted to using a private server and email address during her tenure as secretary of state from 2009 to early 2013.
She has also come under fire from Republicans for the Department’s handling of an attack on the US mission in Benghazi in eastern Libya on September 11, 2012 amid allegations of a cover-up of the facts.
“I’m glad the emails are starting to come out. This is something that I’ve asked to be done as you know for a long time,” Clinton said at a campaign event in New Hampshire.
And she insisted she had released all the emails that had any “government relationship”.
Emails are likely to stalk Clinton as she bids to become the first woman to occupy the Oval Office in the 2016 elections, hoping to slide into the seat once held by her husband, former president Bill Clinton.
A total of 296 emails – out of a trove of 30,000 – sent or received by Clinton were uploaded onto a State Department website on Friday, which promptly crashed under the volume of traffic.
None appeared to contain anything potentially damaging to Clinton as she pursues her White House bid, although some have been heavily redacted.
Some were long memos from a long-time Clinton family friend and adviser, Sidney Blumenthal, using information from “sensitive sources” with access to Libyan officials.
Initially, Blumenthal said then Libyan president Mohammed Megaryef had been told the attacks were “inspired by what many devout Libyans viewed as a sacrilegious Internet video”.
But only hours later on September 12, he sent another long email marked “just in” from his mobile phone.
“Libyan security officials believe that the attack was carried out by forces of the Islamist militia group calling itself the Ansar al-Sharia brigade; working out of camps in the eastern suburbs of Benghazi,” it stated.
Clinton forwarded the email from her account to trusted foreign policy adviser Jake Sullivan, saying: “We should get this around asap.” Sullivan replied: “Will do.”
There were also messages of condolences from senior State Department staff at the deaths of the four Americans, and tributes to Clinton for her speech at Andrews Air Force base when the bodies were brought home.
“Your remarks this afternoon at Andrews were wonderful,” wrote then deputy secretary Bill Burns on September 14. “Thanks for doing so much for our institution on such a sad day.”
Clinton and her staff also closely monitored an appearance by national security adviser Susan Rice when she took to the Sunday morning talk shows on September 16 to discuss the attack.
“She wasn’t asked whether we had any intel. But she did make clear our view that this started spontaneously and then evolved,” Sullivan wrote to Clinton.
“The only troubling sentence relates to the investigation specifically,” he added, after Rice told ABC television’s “This Week” that the administration would have to wait and see if things “might have unfolded differently in different circumstances”.
Many of the other emails appear to be press articles being forwarded to Clinton by her chief of staff Cheryl Mills and other aides.
“The emails we release today do not change the essential facts or our understanding of the events before, during, or after the attacks,” State Department deputy spokeswoman Marie Harf insisted.
Part of one email from Sullivan relating to the arrests of suspects in the Benghazi case was classified at the request of the FBI, even though it was not deemed to be secret at the time it was sent.
Clinton has said she used her own server and email address for “convenience” and turned over some 55,000 paper pages to the State Department from emails sent on two private addresses (email@example.com and firstname.lastname@example.org).
A State Department team has been busy digitising them and plowing through the emails to black out any classified or sensitive information.
