The FBI has launched a criminal leak investigation focusing on an Atlantic magazine journalist who wrote a deeply unflattering account last month of Director Kash Patel's work habits, two people familiar with the matter told MS NOW. The sources said the so-called insider threat investigation is highly unusual because it did not stem from a disclosure of classified information and because it is focused on leaks to a reporter. The agents involved are part of an insider threats unit based in Huntsville, Alabama, the sources added. Typically, leak investigations look into government officials who may have disclosed state secrets or classified documents. Journalists who receive and publish such information have typically only been involved as potential witnesses.
