Wait, they can't go back that far. Federal limit is 5 years and even with a 3 year extension...they can't do anything with that information if any truly exists.
The MUELLER Witch Hunt is for show! All about covering Hillary/Podesta money laundering with Russia, which is shown in THE PANAMA PAPERS, 2016. Mueller, as head of FBI, actually carried the Uranium sample to Russia (2011?) the facts were published, and I saw it on Twitter. Copy of an e mail reference with his name and plane ticket to Russia meeting approved by Russian Agent. This is smoke and mirrors to protect the corruption during Hillary Sec of State term.
