Hillary Clinton never used just one device.

Despite an explanation that she used a personal email address so she could only carry a single device, documents show that during her time as secretary of state, she emailed her staff via both an iPad and a BlackBerry.

Four emails released by the State Department between Clinton and her senior advisers in response to a 2013 Freedom of Information Act request by the Associated Press seeking emails relating to drone strikes overseas and U.S. surveillance programs over a four-year period offer a limited look — but a look nonetheless — into Clinton's official correspondence.

In one email exchange in September 2011, personal and work matters accidentally mix.

In the instance, adviser Huma Abedin sent Clinton's personal email account an AP story about a drone strike in Pakistan. Clinton mistakenly replied with questions about decorations.

"I like the idea of these," she wrote to Abedin. "How high are they? What would the bench be made of? And I'd prefer two shelves or attractive boxes/baskets/ conmtainers (sic) on one. What do you think?"

Abedin replied, "Did u mean to send to me?" To which Clinton wrote back, "No-sorry! Also, pls let me know if you got a reply from my ipad. I'm not sure replies go thru."

Another email turned over by the State Department shows a summary of a 2011 meeting between Sen. John McCain, R-Ariz., and senior Egyptian officials in Cairo. The email was forwarded to Clinton's private account from Abedin's government email address.

Clinton did use an iPad during her time with the State Department, but primarily to read the news, according to Clinton spokesman Nick Merrill early Tuesday morning.

Earlier this month, Clinton explained she used a personal email address rather than a government one due to convenience and the desire to simply carry one device.

"Looking back, it would have been probably, you know, smarter to have used two devices," Clinton said.

She has since faced scrutiny for the decision, specifically after saying she deleted some 30,000 emails from her personal server due to their "personal" nature. However, in the aforementioned mixing of personal and work matters, it is unclear how she went about handling the emails.

The four emails released this week are the only four the State Department said it could find meeting the terms of one FOIA request. The AP sued the State Department earlier this month to force the release of previously filed FOIA requests, starting in 2010.
