The US's presidential election candidate Hillary Clinton's private email-id was exposed by the Romanian hacker, has now claimed that he also gained access to to the former Secretary of State's "completely unsecured" server.



In an exclusive interview from a prison in Bucharest, Marcel Lehel Lazar, told NBC News that "It was like an open orchid on the Internet, there were hundreds of folders."



Last month only United States extradited him to face charges for hacking accounts of many political elites including Gen. Colin Powell, a member of the Bush family, and former Clinton advisor Sidney Blumenthal.



According to the sources he was escorted to a Virginia jail by FBI agents. The investigators have seen nothing so far to substantiate his claim but that the investigation continues. But still, a former FBI special agent who ran major cyber security probes found his story credible.



"To go on television and admit to a felony you didn't commit seems a little silly," he said.



Seeking this an opportunity the opposition parties charged that national security was compromised and the FBI launched an investigation, Clinton maintained that the server was safe and there were no security breaks.



"It was a lie, clearly, they're a pathological, well-practiced liar," Lazar said.



Clinton's campaign press secretary, Brian Fallon said that, "There is absolutely no basis to believe the claims made by this criminal from his prison cell".



"In addition to the fact that he offers no proof to support his claims, his descriptions of Secretary Clinton's server are inaccurate. It is unfathomable that he would have gained access to her emails and not leaked them the way he did to his other victims. We have received no indication from any government agency to support these claims, nor are they reflected in the range of charges that Guccifer already faces and that prompted his extradition in the first place," Fallon added. "And it has been reported that security logs from Secretary Clinton's email server do not show any evidence of foreign hacking."



A source close to the Clinton case confirmed to NBC News that the FBI's review of her server logs showed no signs of foreign hacking.
