Turning the tables

Mueller spent two years investigating President Trump.  One of the charges was that he committed obstruction of justice by firing FBI Director James Comey.  Now Comey is under investigation for leaking classified information.  See

Report of Investigation of Former Federal Bureau of Investigation Director James Comey's Disclosure of Sensitive Investigative Information and Handling of Certain Memoranda

I don't have time to read it, but here is part of the introduction:
Between January 6, 2017, and April 11, 2017, while Comey was Director of the FBI, he memorialized seven one-on-one interactions that he had with President-elect and President Donald J. Trump. In June 2017, following Comey’s removal as FBI Director, the FBI reviewed the Memos to determine if any of the Memos contained classified information. The FBI determined that Memos 1 and 3 contained information classified at the “SECRET” level, and that Memos 2 and 7 contained small amounts of information classified at the “CONFIDENTIAL” level. 

And here is part of the conclusion:
Comey had several other lawful options available to him to advocate for the appointment of a Special Counsel, which he told us was his goal in making the disclosure. What was not permitted was the unauthorized disclosure of sensitive investigative information, obtained during the course of FBI employment, in order to achieve a personally desired outcome.
