Hillary Clinton told FBI investigators last month that she did not have a personal computer inside the area within her home designed for viewing classified information known as a SCIF.

But three different witnesses told the FBI Clinton did indeed use personal computers inside the SCIFs at her Washington, D.C., and Chappaqua, N.Y., homes.

The contradiction in Clinton's statements was just one of many that was exposed in the scathing 58 pages of notes released by the FBI Friday from its investigation of Clinton.

In another, Clinton told the FBI agents who interviewed her in July that State Department employees were well aware of her private email use because she contacted them frequently from her personal address.

"However, some State employees interviewed by the FBI explained that emails from Clinton only contained the letter 'H' in the sender field and did not display her email address," the FBI wrote.

Clinton has said Colin Powell advised her to use private email because he did so during his time as secretary of state.

But the conversation described in the FBI's notes indicated Powell actually warned Clinton about the dangers of using a personal account, cautioning Clinton to "be very careful" and to make sure details of her private email use never became public. The notes also showed Powell requested permission to use a personal address because the State Department servers at that time did not allow communication with anyone outside the government, while Clinton engaged in her email practices without the consent of her agency.

The FBI's notes raise questions about a number of Clinton's public and even private statements about her email use.

For example, she told investigators she did not recall ever receiving training on how to handle classified information, but she signed forms that have since been made public by the State Department indicating she was instructed about the protection of sensitive material.
