A timeline of Clinton’s email “gaps” circulated internally among State Department officials this year shows that Clinton did not send or receive a single email over a period of almost two months after being sworn in as the nation’s top diplomat in January 2009.

After receiving her first email through her private address in March of that year, she waited nearly another month before sending her first email, the timeline shows.

Then at the end of her time at the department, Clinton went for another month without sending a single email.

Email is far from the only — or even primary — way that top diplomatic figures such as Clinton would communicate with officials around the globe.
