Former Senate Judiciary Committee Chairman and current Senate Finance Committee Chairman Chuck Grassley revealed late Wednesday that the State Department has found 30 incidents of mishandling classified information under Secretary Hillary Clinton.

"The State Department has identified 23 violations and seven infractions in its ongoing review of the mishandling of classified information associated with former Secretary of State Hillary Clinton’s use of a non-government email server for official business. The revelations came in an update to Senator Chuck Grassley (R-Iowa), who has been leading congressional oversight into the mishandling of classified information and the alienation of federal records," Grassley's office released in a statement. "The State Department’s update noted that 15 individuals were assessed for violations or infractions, and some of them were found culpable of multiple security incidents. Individuals with a security violation or three or more infractions have been referred to the proper officials for documentation and possible discipline. The department also acknowledged that the number of violations and infractions may change as the investigation progresses."

Grassley has been requesting information about the mishandling and exposure of top secret, classified information on Clinton's unsecure, personal server for years. The State Department has slow walked their response to his inquiries and has failed to pull security clearances from individuals found to have mishandled highly sensitive information.

"Consistent with longstanding policy, the Department does not release the names of current or former employees participating in the security incident program. However, in the spirit of cooperation, the Department can share with you certain information about the status of the ongoing review. To this point, the Department has assessed culpability to 15 individuals, some of whom were culpable in multiple security incidents. DS has issued 23 violations and 7 infractions incidents under 12 FAM 550. This number will likely change as the review

progresses," a letter from the State Department to Grassley states. "In every instance in which the Department found an individual to be culpable of a valid security violation or three or more infractions, the Department forwarded the outcome to the Bureau of Diplomatic Security's Office of Personnel Security and Suitability (DS/PSS), to be placed in the individuals' official security file."

While the FBI did not charge Clinton with a crime for repeatedly mishandling classified information, former Director James Comey did say the former Secretary of State and her staff were "extremely careless."

"There is evidence they [Clinton and staff] were extremely careless in their handling of classified information," Comey said in July 2016. "One hundred-and-ten emails in 52 email chains have been determined by the owning agency to contain classified information at the time they were sent or received. Eight of those chains contained information that was top secret, at the time they were sent, 36 of those chains contained secret information and eight contained confidential information at the time."
