A new document released by the FBI late this afternoon in another Friday document dump adds another damning piece of evidence to the inexplicably closed Clinton email case.

An employee at Platte River Networks, the company that managed Hillary Clinton’s emails after she left the State Department, sent a work ticket that referred to the “Hilary [sic] coverup [sic] operation” (Hillary cover-up operation) after Clinton’s team had asked the company to modify her email system so that it would automatically delete messages after 60 days.

Via the Washington Examiner:

The revelation came in 189 pages of FBI documents made public Friday evening amid controversy over the five immunity deals extended to aides involved in the case — including one that protected a key employee at Platte River from prosecution. The unnamed employee told FBI agents that his reference to the “cover-up” was a joke.

The FBI apparently took his word for it.

“The fact an IT staffer maintaining Clinton’s secret server called a new retention policy designed to delete emails after 60 days a ‘Hillary coverup operation’ suggests there was a concerted effort to systematically destroy potentially incriminating information,” said Jason Miller, senior communications advisor for the Trump campaign, in a press release. “It’s no wonder that at least five individuals tied to the email scandal, including Clinton’s top State Department aide and attorney Cheryl Mills, secured immunity deals from the Obama Justice Department to avoid prosecution.”
