On CNN's 'State of the Union' on Sunday morning, host Jake Tapper asked Hillary Clinton campaign manager Robby Mook about the latest turn in the Hillary Clinton private email server investigation. Hidden within the 189 pages of FBI documents <a href="http://www.realclearpolitics.com/video/2016/09/25/rudy_giuliani_it_looks_like_fbis_only_reason_for_investigating_clinton_emails_is_to_hand_out_immunity_deals.html">made public Friday afternoon</a> are emails from employees of Platte River Networks, the firm which managed Clinton's email server, describing the "Hillary Coverup Operation" sent after Clinton's staff asked them to begin wiping emails in December 2014. <blockquote>JAKE TAPPER, CNN: There was a document dump on Friday where we learned from the FBI that an I.T. contractor managing Hillary Clinton's private e-mail server made reference to the "Hillary coverup operation" in a work ticket. He used that after an aide asked him to automatically delete emails after 60 days. This I.T. worker thought he was covering something up, no? ROBBY MOOK: I'm glad you asked this question. A lot of this stuff is swirling around out the ether. It's important to pull back and look at the facts. The FBI did a comprehensive and deep investigation into this and at the conclusion of that, FBI Director Comey came out and said to the world that there was no case here. That they did not have evidence of wrongdoing on Hillary's part. TAPPER: So what's the "Hillary cover-up operation" that the I.T. worker was referring to? MOOK: This is the perfect example of what's going on here. The Republicans in the House are selectively leaking documents for the purpose of making Hillary look bad. We asked FBI to release all information they shared with the Republicans so we can get the full picture. Again I would trust the career professionals at the FBI and Justice Department who looked into this matter, concluded there was no case [more] than I would Republicans who are selectively leaking information. </blockquote> Clinton's team asked her IT staff to set up the server so that emails would automatically self-delete after 60 days. A Platte River Networks employee allegedly told the FBI that the use of the term "coverup" was a "joke."
