More of Clinton’s emails from her time as secretary of state are released by the State Department, due to Freedom of Information Act (FOIA) lawsuits by Judicial Watch. In 2015, Clinton claimed that she didn’t start using her new private email address until March 18, 2009. But all these emails date from before then.
There are 15 emails using her old email address from January 22, 2009 (one day after she became secretary of state) to February 26, 2009. There are another 108 emails using her new email address (hosted on her private server) from January 30, 2009 to March 8, 2009. (Judicial Watch, 5/12/2016) (US Department of State, 4/29/2016) (US Department of State, 4/29/2016) (US Department of State, 4/29/2016)
LawNewz notes that this email release “contradicts claims made by Clinton and her campaign that she did not begin using the private e-mail server until March 2009. […] The dates of the newly released e-mails also appear to contradict a declaration signed by Clinton, under penalty of perjury, saying she surrendered all her work-related e-mails to the State Department on December 5, 2014.” (LawNewz, 5/13/2016)
