Hillary Clinton said she didn't know what the 'C' markings in emails stood for
The State Department determined that one email chain contained information that is currently classified at the "confidential" level, according to the documents.
But the emails apparently didn't contain any header or footer markings indicating that some information in the message was classified.
The FBI described what it found:
"The FBI identified three email chains, encompassing eight individual email exchanges to or from Clinton's personal email accounts, which contained at least one paragraph marked '(C),' a marking ostensibly indicating the presence of information classified at the CONFIDENTIAL level."
The State Department didn't specify whether the information in the emails was classified at the time the messages were sent, but markings meant to indicate that the information is "confidential" suggests it might have been.
Although one email chain contained information that is currently classified, the other two chains referenced in the FBI documents are currently unclassified.
When presented with the findings, Clinton told investigators that she wasn't aware of what the markings meant. From the FBI notes:
"Clinton stated that she did not know what the '(C)' meant at the beginning of the paragraphs and speculated it was referencing paragraphs marked in alphabetical order."
The documents the FBI released pertain to its investigation of Clinton's use of the server while she was secretary of state. She is currently the Democratic nominee for president.
The FBI did not recommend that the Justice Department file charges against Clinton for her use of the private server, but Director James Comey said Clinton was "extremely careless" in handling classified information.
