Hillary Clinton's email problems reportedly now also involve her staff.

FOX News Radio's Jon Decker reports from the White House:

A member of Hillary Clinton's staff at the State Department emailed classified information to a staffer at the Clinton Foundation.

The Free Beacon is reporting that Cheryl Mills, Clinton's Chief of Staff, sent the email about the Congo government to the Clinton Foundation in 2012.

An attorney for Mills said that she never knowingly transmitted classified information.

The FBI is currently attempting to recover deleted emails to and from then Secretary Clinton as part of a federal investigation into Clinton's use of a private server.
