Two of the four classified emails found on Hillary Clinton's private email server were "Top Secret," McClatchy is reporting. The inspector general for the intelligence community told key members of Congress about the top-secret classification, Fox News Channel confirmed on Tuesday. The other two emails are being reviewed by the State Department to determine their classification.Additionally, all of Clinton's emails, including those that require a security clearance to read, are in the possession of her personal attorney, Fox reported."This information revealed by the inspector general makes it even more important that the FBI and the State Department secure these documents," Judiciary Committee Chairman Chuck Grassley said on Tuesday. "To date, the two agencies most critical to securing this information have failed to assure the American people that they are taking the necessary steps to protect America's national security interests."The attorney has the information on a thumb drive, spurring fears it could have been hacked. Both inspectors general noted that the information was not marked classified at the time it was given to the attorney. The FBI did not comment, according to McClatchy.GOP presidential front-runner Donald Trump addressed the situation in his press conference Tuesday night, saying "If they judge it fairly, she's got a very big problem."Clinton denied during her March press conference on the subject that she sent any classified information over her private server when she was secretary of state. The emails in question were sent by her aides."We will follow the facts wherever they lead, to include former aides and associates, as appropriate," Douglas Welty, a spokesman for the State Department’s inspector general, told McClatchy.Clinton is not a target, McClatchy, which broke the story, reported. But the State Department inspector general's office did not say who was. The news organization initially was referred to the Intelligence Community inspector general’s office, which told McClatchy it is not involved in an inquiry into Clinton aides and added that the State Department is denying it full access to aides' emails.Even though Clinton is not currently being investigated, the ongoing probe is threatening her front-runner status as more voters tell pollsters they don't consider her honest and trustworthy. A new Public Policy Polling survey out Tuesday showed Clinton losing to four Republican candidates in Iowa. Clinton on Tuesday directed that her server be turned over to the Justice Department. She also directed that her lawyer's thumb drive be turned over.Clinton has previously said the server's hard drive was wiped after work-related emails were given to the State Department.At least four of Clinton's top aides have turned over their records, including copies of work emails on personal accounts, to the State Department, McClatchy reported. State is collecting them in response to Congressional subpoena. The personal emails of six other aides also have been requested.Senate committee chairmen Richard Burr of North Carolina, Bob Corker of Tennessee and Ron Johnson of Wisconsin asked both inspectors general to audit the personal emails for possible work-related communications."As outlined in the joint letter with his colleagues, Chairman Burr has expressed concern that State Department aides may have transmitted sensitive or classified information in an insecure manner," Burr spokesman Becca Glover Watkins told McClatchy. "Chairman Burr expects that the IGs will conduct their investigations as requested."That may not be happening, however, since the Intelligence Community inspector general is deciding which emails to review and how they should be classified.Intelligence Community Inspector General spokeswoman Andrea Williams told McClatchy her office "never had access to any emails other than those provided to the State Department by former Secretary Clinton."The State Department and the Intelligence Community inspectors general remain at odds over jurisdictional issues."I think the headline is that there's nothing but murkiness and non-answers from the State Department," Gawker lawyer Bradley Moss told McClatchy. The media group is suing for access to the emails."I think the State Department is figuring this out as it goes along, which is exactly why no one should be using personal email to conduct government business," Moss said.Clinton has admitted in an affidavit that her deputy chief of staff Huma Abedin had an account on her personal server. But she said her chief of staff Cheryl Mills did not.Mills, deputy chief of staff Jake Sullivan and Deputy Assistant Secretary of State Philippe Reines all have turned over records to the State Department, including personal emails.Mill had planned to delete her emails after turning over copies, but U.S. District Court Judge Emmet Sullivan has ordered no records be destroyed as part of a Judicial Watch Freedom of Information Act lawsuit.Clinton had aides sort through all of her emails, and said she turned over all of them that were work-related, a total of 30,490. She said she deleted 31,830 emails that were personal.The State Department discovered, however, that all or parts of at least 15 of Clinton's emails were missing when longtime friend Sidney Blumenthal gave the House committee some of his personal emails sent to Clinton.
