It turns out presidential candidate Hillary Clinton didn’t hand over all the work-related emails from the personal account she used during her time as secretary of state. The State Department has received 15 emails between Clinton and her longtime adviser Sidney Blumenthal that Clinton did not originally hand over, The New York Times reports. Blumenthal did not work for Clinton during her time as secretary of state, but sent her regular intelligence memos on Libya. Blumenthal gave those 15 emails to a House committee investigating the 2012 Benghazi attacks; the committee then gave them to the State Department. Clinton has said she gave the State Department around 30,000 emails, but deleted around the same number of emails because they were not work-related.
