The FBI will interview Hillary Clinton within the next few weeks in the latest leg of its probe into her use of an unsecured email system while she served as secretary of state, CBS News reported Friday.
The Democratic front-runner's presidential campaign has remained adamant that the review "will conclude that nothing inappropriate took place."
The FBI last month interviewed Clinton's closest ally Huma Abedin in its Washington, D.C. office.
While the investigation is ongoing, investigators said they haven’t discovered evidence that shows Clinton "willfully" violated federal law.
The FBI and the Justice Department have spent more than a year probing Clinton's private email server in an attempt to determine whether she mishandled classified information during her time serving as secretary of state.
Clinton has denied wrong doing throughout her campaign and has argued that none of the emails sent or received on her private server were marked classified at the time.
Government officials found that more than 2,000 emails on Clinton’s server contain classified information, though none was marked classified on her personal email. Twenty-two messages have been deemed "top secret," the highest classification level, and were withheld from public release
