Platte River Networks (PRN) is the computer company that has been managing Clinton’s private server. In August 2015, the Senate Homeland Security Committee asked PRN for a staff-level briefing on the server, and got one later that month.
In early September 2015, Congressional investigators communicate with Ken Eichner, a lawyer working for PRN, asking to interview five employees in Denver, Colorado, where PRN is located. But on September 17, 2015, Eichner writes in an email, “I am going to respectfully decline [permission for] any interviews.”
In September 2015, some PRN employees are interviewed by the FBI, but details of that remain unknown. In November 2015, it will be reported that PRN isn’t cooperating with Congressional investigators at all, and isn’t allowing Datto, Inc., a company it subcontracted to help back up Clinton’s server, to cooperate either.
