In the closing days of the 2020 election, the New York Post published emails it obtained from President Trump's then lawyer Rudy Giuliani purporting to show Hunter Biden using his influence with his father to obtain favorable treatment for a Ukrainian company. Fifty-one former intelligence community officials, including Jim Clapper, Mike Hayden, John Brennan, and Leon Panetta, wrote a public letter warning that the emails had "all the classic earmarks of a Russian information operation" and that if they were correct it was important for Americans to be aware that "this is Russia trying to influence how Americans vote in this election." The order revokes any active security clearances held by the signatories to the letter and directs an investigation of any other related conduct. The Order also revokes the security clearance of President Trump's former National Security Advisor John Bolton for the purported reckless disclosure of sensitive information in his memoir.
