Republican lawmakers are expressing annoyance that, although the FBI has passed Congress the documents detailing the investigation into the Clinton email scandal, the documents are not actually readable due to the format in which they were handed over.

According to Fox News, the Senate Judiciary Committee Chairman, Republican Chuck Grassley claimed that documents handed over by the FBI are largely unreadable because they published classified material together with unclassified material, so only a select few have the clearance to read the evidence.

“As I have expressed to the FBI in the past, it is inappropriate to unnecessarily mingle classified and unclassified information,” Grassley wrote, and called the FBI's formatting choice "regrettable."

The complaint comes after the FBI provided Congress with documents detailing their investigation into Clinton's usage of a private server during her time as Secretary of State. They warned Congress that the material they were providing contained "classified and other sensitive information and is being provided with the expectation it will not be disseminated or disclosed without FBI concurrence.”

Clinton has claimed in the past that she merely used a private server "out of convenience." She did, however, concede that it "would have been better" to have two separate accounts for work and personal affairs.
