Hillary Clinton, former U.S. secretary of state, listens to a question during a news conference at the United Nations (UN) in New York, U.S., on Tuesday, March 10, 2015. Clinton defended the legality of her use of a private e-mail account and server while she served as secretary of state, saying that she had done so out of a desire for convenience but should have used a government account for work purposes.
