Multiple memos Comey wrote as personal recollections of his interactions with President Trump about the Russia investigation contained classified information.

Comey told the Senate Intelligence Committee last June that he shared at least one of the memos, which he considered personal documents, with a law professor at Columbia University. He then asked that professor to leak the information from one memo to the media in the hopes of increasing pressure to get a special prosecutor named in the Russia investigation.

Comey testified that he believed his personal memos were unclassified.

President Trump fired Comey in May.
