The FBI has expanded its investigation of Hillary ClintonHillary Rodham ClintonInfowars' Alex Jones apologizes for pushing 'Pizzagate' conspiracy theory Warren: 'Today is a great day... but I'm not doing a touchdown dance' Hollywood stars weigh in on GOP pulling healthcare bill MORE's use of a private email server during her time as secretary of State to determine whether her Clinton Foundation work violated public corruption laws, according to Fox News.
The report is based on accounts by three unnamed sources.
"The agents are investigating the possible intersection of Clinton Foundation donations, the dispensation of State Department contracts and whether regular processes were followed," one of the sources told Fox.
The FBI's investigation up until now has been focused on the classified information shared in the emails.
The State Department has released over 3,000 emails from Clinton's private server, 1,340 of which were deemed classified at some level.
One of the Fox sources also said that the FBI is especially eager to pursue a high-profile public corruption case in the wake of what they believe was overly lenient treatment of former CIA Director David Petraeus, who pleaded guilty to a misdemeanor last year for mishandling classified information after it was revealed that he had given classified information to his mistress.
Clinton, who is the front-runner in the Democratic presidential primary, has denied knowingly sending or receiving classified information over her private server.
