For roughly four months during her tenure as secretary of State, Hillary Clinton did not send a single work-related email, according to State Department information revealed as part of an ongoing lawsuit.

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 for a month and a half days after being sworn in as the nation’s top diplomat in 2009.

After receiving her first email through her private email address in March of that year, she waited nearly another month before sending anything out, 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 like Clinton would communicate with officials around the globe.

But to conservative critics of the Democratic presidential front-runner, the gaps in email usage reek of impropriety, and suggest that Clinton has hid some records from the government.
