Libby was wrongly accused of outing a CIA agent, and convicted of related offenses.
Plame’s identity, it turned out, was leaked to journalist Robert Novak not by the White House, but by Deputy Secretary of State Richard Armitage.It should be noted Armitage suffered nothing at all for the leak, was never even charged. Involved in the Libby prosecution were "Special Counsel Patrick Fitzgerald and then-Deputy Attorney General James Comey.”
That's the James Comey fired by Trump, and the sore loser who is now doing a book tour smearing the President at every stop. It is devoutly to be hoped the IG report previewed below results in a Comey felony prosecution.
