The Federal Bureau of Investigation (FBI) has started examining the security of the private email setup of Hillary Rodham Clinton, two government officials have revealed. The bureau had contacted a technology firm based in Denver, Co. that helped run the rare computer system in the past week.

It also contacted Clinton's lawyer, David Kendall, asking him about a thumb drive, which contains copies of emails sent by Clinton during her term as secretary of state, currently in his possession and its security, according to the Washington Post.

"Quite predictably, after the [intelligence community's inspector general] made a referral to ensure that materials remain properly stored, the government is seeking assurance about the storage of those materials," Kendall told Fox News.

Kendall also revealed that he and Clinton were "actively cooperating" with the investigation, but Clinton's advisers were more keen to classify the Post's report as old news on Tuesday night.

"WaPo story tonite doesnt change anything we knew 10 days ago after NYT fixed botched report: IG sent ask to DOJ to confirm emails are secure," Clinton's press secretary Brian Fallon Tweeted shortly after the story was published, according to CNN.

Last month, federal officials asked the U.S. Justice Department to launch an inquiry on the exclusive use of a personal email account of Clinton and home-based server during her time as secretary of state.

This is because the State Department and intelligence agencies believe that Clinton may have mismanaged classified information when it was discovered that her private account may possibly contain hundreds of classified emails, HNGN previously reported.
