FBI agents went to James Comey's residence and retrieved a secret, previously unreported memo he drafted the night before the agents arrived, well after he was fired as FBI Director, according to bureau documents released Wednesday in response to a Freedom of Information Act request by the transparency group Judicial Watch. Additionally, Comey told agents "spontaneously" that, to "the best of his recollection, two [memos] were missing," according to the documents. A source familiar with the probe has confirmed to Fox News that the DOJ Inspector General's office is reviewing whether Comey's memos improperly contained classified information, among other matters.
