IT firm hired by Hillary Clinton: It's 'highly likely' there's a backup of emails she deleted

The IT firm hired by Hillary Clinton to oversee her private server told ABC that is "highly likely" a backup copy of the server was made, meaning that any emails Clinton deleted prior to handing the server over to investigators may still be accessible.

Being able to access the deleted emails via a backup server would likely make investigators' job much easier, cybersecurity expert Alex McGeorge of Immunity, Inc. told Business Insider.

Over the weekend, Clinton reiterated that she "never sent classified material on my email, and I never received any that was marked classified."

Clinton's unusual email system, currently under investigation by the FBI, was originally set up by a staffer during Clinton's 2008 presidential campaign. It replaced another private server used by her husband, former President Bill Clinton.

The new server was run by Bryan Pagliano, who had worked as the IT director on Hillary Clinton's campaign before joining the State Department in May 2009. In 2013 - the same year she left the State Department - Clinton hired Platte River to oversee the system.

"My big issue here is do you want a small firm with little/no Government experience or contracting (according to what's being reported) and no stated security expertise to be in charge of the email system for our Secretary of State?" McGeorge said.

"That is fundamentally ridiculous."

There is no evidence that Clinton broke the law, but her campaign is concerned nonetheless.
