"One of the prosecutors who brought the case against I. Lewis “Scooter” Libby says President Trump’s pardon of the ex-top aide to former Vice President Dick Cheney sends a not-so-subtle message to potential witnesses in special counsel Robert Mueller’s Russia investigation: Stay loyal to Trump and Trump will stay loyal to you.

“I don’t see any other logic to it,” Peter Zeidenberg, top deputy to the special counsel in Libby’s case, Patrick Fitzgerald, said in a recent interview for Yahoo News’ Skullduggery podcast."

It was no loyalty pledge, Trump pardoned Libby to send a Message to Patrick Fitzgerald who was special council over the Prosecution of Libby.

Who hired Fitzgerald?

James Comey.
