Few State Department officials appear to know that Clinton has a private email server in her house.

However, news about her frequent BlackBerry use soon spreads among the Department’s security officials. They are concerned about “Mahogany Row,” the seventh floor offices of Clinton and her top aides.

A decade earlier, Russian spies placed a listening device in a chair on that floor. Since then, on multiple occasions, hackers had breached computers in the State Department and other federal agencies.

State Department security officials are particularly concerned that Clinton’s BlackBerry could be compromised, and they worry that she could be setting a “bad example” for others in the department. They craft a memo that discusses the risks, which will be sent out on March 6. (The Washington Post, 3/27/2016)
