In new documents released by the FBI summarizing the agency’s interview with Hillary Clinton about her email server, Clinton says she was unaware that she had to save her emails when she left office.

Clinton told the FBI on July 2 that she recalls no briefing about preserving or producing her records when she transitioned out of her post as Secretary of State. The document notes that her transition coincided with her 2012 concussion and blood clot: “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.”

Clinton also said that when emails were marked (C), which State determined to hold confidential information, she did not know what the (C) meant and she thought it had to do with alphabetizing paragraphs.

“Hillary Clinton’s answers to the FBI about her private email server defy belief. I was absolutely shocked to see that her answers to the FBI stood in direct contradiction to what she told the American people,” Donald Trump said in a statement. “After reading these documents, I really don’t understand how she was able to get away from prosecution.”

The FBI interviewed Clinton as part of its investigation into her use of a private email server while Secretary of State. Days later, FBI Director James Comey recommended that no criminal charges be brought against Clinton, though he said the agency found her to be “extremely careless” handling classified material.

The material is included in 58 pages of documents from the FBI’s now-closed investigation. The documents include a summary of agents’ interviews with Clinton and her aides as well as technical details about how the server was designed.
