Former Secretary of State Hillary Clinton withheld from the State Department several emails related to Libya, the State Department confirmed Thursday night — calling into question her insistence that she has handed over her complete public record.

The 2016 Democratic front-runner did not hand over 15 exchanges with longtime Clinton ally Sidney Blumenthal on the security situation in the Middle Eastern nation. The existence of the new correspondence only came to light days ago after Republicans subpoenaed the former Clinton White House adviser’s records and he turned them over.

Clinton has said she cooperated with the House Benghazi Committee investigation by handing over all work-related communications, which she stored on her own personal server against official record-keeping rules.

“This confirms doubts about the completeness of Clinton’s self-selected public record and raises serious questions about her decision to erase her personal server — especially before it could be analyzed by an independent, neutral third-party arbiter,” Benghazi panel Chairman Trey Gowdy said in a statement.

The South Carolina Republican said the implications go “far beyond Libya, Benghazi and our committee’s work.”

“This conclusively shows her email arrangement with herself, which was then vetted by her own lawyers, has resulted in an incomplete public record,” he continued.

Clinton has come under fire for circumventing government rules instead of using an official State Department email address, with critics accusing her of hiding behind a shroud of secrecy. Clinton, for her part, turned over more than 30,000 work emails to state as part of its document production to the Benghazi committee. The rest, she said, were personal in nature — about Chelsea’s wedding or yoga, she said.

Then, her team wiped her server clean, they say.

Barred from working at the State Department by the Obama administration, Blumenthal was being paid $10,000 a month by the philanthropic Clinton Foundation at the time. He was also advising friends working on a new business venture in Libya — and one of those business partners is said to have been the author of the intelligence memos Blumenthal passed along to Clinton.

Blumenthal told the committee the emails were unsolicited, but Republicans say a number of the emails Clinton did not turn over suggests they were, including responses where she encouraged her old friend to continue writing.

“These new messages in many instances were Clinton’s responses, which clearly show she was soliciting and regularly corresponding with Sidney Blumenthal — who was passing unvetted intelligence information about Libya from a source with a financial interest in the country,” the panel statement continues. “It just so happens these emails directly contradict her public statement that the messages from Blumenthal were unsolicited.”

Democrats on the panel, however, have challenged that assertion and questioned Gowdy’s definition of “unsolicited,” arguing that simply a response to an email does not constitute solicitation.

State, meanwhile, says it is working quickly to produce all the emails it does have.

“We have confirmed that the emails Secretary Clinton provided the Department include almost all of the material in Mr. Blumenthal’s production,” a state official said in a statement. “The State Department is working diligently to review and publish the 55,000 pages of emails we received from former Secretary Clinton, according to FOIA standards so they are available to the general public and the media. All of the materials that she provided will be reviewed as part of this effort.”
