Oops!  Under oath, too.  Breitbart reports:

Former Secretary of State Hillary Clinton has been caught in another lie regarding her private email accounts that she used during her tenure at the agency.

Though her lawyer David Kendall told the House Select Benghazi Committee that Clinton’s “hrod17@clintonemail.com” email address “was not an address that existed during Secretary Clinton’s tenure as Secretary of State,” new emails obtained by the New York Times show that Clinton did indeed use that email address for official business.

Clinton emailed Jake Sullivan, her deputy chief of staff, to his “Sullivanjj@state.gov” government email account on at least three occasions while she was secretary of state from her “hrod17@clintonemail.com” account.

Clinton sent Sullivan emails from her “hrod17@clintonemail.com” account on April 8, 2011, January 5, 2012, and August 28, 2012, according to emails the Times published. Clinton served as secretary of state from January 21, 2009 to February 1, 2013.

Another “honest mistake,” of course.
