In December 2012, near the end of Clinton's tenure as Secretary of State, a nonprofit group called Citizens for Responsibility and Ethics in Washington, or CREW, filed a FOIA request seeking records about her email. CREW received a response in May 2013: "no records responsive to your request were located." Emails sent to Clinton's private clintonemail.com address were first discovered in March 2013, when a hacker named "Guccifer" widely distributed emails sent to Clinton from Sidney Blumenthal, which Guccifer obtained by illegally accessing Blumenthal's email account. The emails dealt with the 2012 Benghazi attack and other issues in Libya and revealed the existence of her clintonemail.com address.
