Hillary Clinton told the FBI she did not know she was required to keep records of her emails when she left office

The FBI on Friday released 11 pages of notes from its July 2 interview with

Hillary Clinton, as well as a 47-page summary of its now-closed investigation into Clinton’s use of a private email server during her time as secretary of state.

According to the documents, Clinton said that she did not know she was required to keep records of her emails when she left office, and that she did not recall any briefing or training instructing her to do so. Clinton told the FBI that, because of a concussion and blood clot she suffered in 2012, she did not recall all briefings she received as she was transitioning out of office. “Because of her doctor’s advice, she could only work at State for a few hours a day and could not recall every briefing she received,” the document noted.

Clinton also told the FBI that she did not understand that emails marked with a “C” meant they contained classified information.

The Democratic presidential nominee also said she relied on her subordinates’ judgement when emailing her sensitive information on her private email system.

“Clinton did not recall receiving any emails she thought should not be on an unclassified system,” the FBI notes said. “She relied on State official to use their judgment when emailing her and could not recall anyone raising concerns with her regarding the sensitivity of the information she received at her email address.”

Politico writes that, “Taken together, her responses to questions from FBI investigators reveal a high-level government executive who apparently had little grasp of the nuances and complexities around the nation’s classification system – a blind spot that helped allow classified communications to pass through her private email server.”

The FBI took the unusual step of making its notes on Clinton’s interview and investigation public on Friday in response to numerous Freedom of Information Act requests.

“Today the FBI is releasing a summary of former Secretary of State Hillary Clinton’s July 2, 2016 interview with the FBI concerning allegations that classified information was improperly stored or transmitted on a personal e-mail server she used during her tenure,” the agency said in a statement. “We also are releasing a factual summary of the FBI’s investigation into this matter.”
