Clinton is frustrated, because she insists on using her personal BlackBerry device for all her emails, but she is not allowed to take it into her suite of offices where she works every day. The BlackBerry is considered a security risk, as it could be hijacked by hackers and turned into a listening device, so she always has to put it into a lockbox before entering her office.
On this day, she and her top aides have a meeting about this. Clinton, her chief of staff Cheryl Mills, and others meet with five National Security Agency (NSA) officials and security officials from the State Department and other agencies. They discuss ways for Clinton and her aides to use their BlackBerrys in secure rooms, but no easy solution is found.
Clinton continues to use her BlackBerry after the meeting while others keep trying to find a solution. Apparently, all the security officials in the meeting are unaware that Clinton’s emails are being stored on a private server in her house.
The Washington Post will later report, “Those officials took no steps to protect the server against intruders and spies, because they apparently were not told about it.” (The Washington Post, 3/27/2016)
