March 31, 2015: A Platte River Networks employee talks to two of Clinton’s lawyers shortly after deleting and wiping all of Clinton’s emails from her server.

Platte River Networks (PRN) is a computer company managing Clinton’s private server. PRN employee Paul Combetta will later admit to the FBI that he deleted all of Clinton’s emails from her server and then used the computer program BleachBit to permanently eliminate the emails. This is despite the fact that he claims he had only been told by one of Clinton’s lawyers (and her former chief of staff) Cheryl Mills back in December 2014 to change the email retention policy on Clinton’s account.

On March 25, 2015, there was a conference call between PRN employees and members of former President Bill Clinton’s personal staff. On March 31, 2015, there is another conference call. Combetta will later say he made the deletions at some point between the two calls.

Details about the second call are murky because the FBI only discovered it took place due to discovering a PRN work ticket about it. The ticket mentions PRN employees talking to Clinton’s personal lawyer David Kendall as well as her lawyer Mills. But when Combetta was asked about it, according to the FBI, “PRN’s attorney advised [him] not to comment on the conversation with Kendall, based upon the assertion of the attorney-client privilege.”

In 2016, Mills will be interviewed by the FBI. She will state that she was unaware that Combetta made such deletions and modifications in March 2015. This presumably would mean they were not discussed in the second conference call, or any time after that. Clinton will also be interviewed in 2016, and she will also claim she was unaware of the March 2015 email deletions. (Federal Bureau of Investigation, 9/2/2016)
