Democratic presidential front-runner Hillary ClintonHillary Rodham ClintonWikiLeaks claims Obama hacking probe is investigating WikiLeaks Is Van Jones another conflict of interest headache for CNN? The Hill's 12:30 Report MORE’s personal email server hosted two “top secret” emails, according to a new report.
A special intelligence review finished on Monday has concluded that the messages held the nation’s highest classification of government intelligence when the former secretary of State received them in 2009 and 2011, The New York Times reported.
The Times reported that one of messages contains information about North Korea’s nuclear program.
State Spokesman John Kirby on Tuesday said the department's review of Clinton's communications remains ongoing, adding that no final determination has been made on whether any sensitive national intelligence was included in them.
"Classification is rarely a black and white question and it is common for the State Department to engage internally and with our interagency partners to arrive at the appropriate decision," Kirby said.
"For our part, the State Department is committed to getting the classification analysis right, which includes ensuring that information is neither over nor under classified prior to public release," he continued.
"At this time, any conclusion about the classification of the documents in question would be premature," Kirby added.
Voter concerns about Clinton’s server are gradually eroding support for her 2016 presidential campaign across multiple national polls.
Clinton vowed on Monday that she would not apologize for using the server.
“What I did was allowed,” she told The Associated Press in Iowa.
The former first lady additionally pushed back against charges that the controversy is hurting her 2016 presidential campaign.
"I have worked really hard this summer, sticking to my game plan about how I wanted to sort of reintroduce myself to the American people."
