In late August 2016, the FBI acquired some reports from what would later be known as the Steele dossier. In late July, the FBI opened an investigation into the Trump campaign. Comey asked President Obama for permission to write an op-ed, which would warn the public that the Russians were interfering in the election. The president denied the request. CIA director John O. Brennan then gave an unusual private briefing on the Russians to Senate minority leader Harry Reid; Reid then publicly referred to the briefing. Comey, however, refused to confirm—even in classified congressional briefings—that the Trump Campaign was under investigation. In early October, meetings were held in the White House Situation Room; National Security Advisor Susan Rice argued that the information should be released, while Comey argued that disclosure was no longer needed.
