Clinton says she sent no classified emails

Democratic presidential candidate Hillary Rodham Clinton is standing firm that she never sent or received emails on her homebrew email server that were marked classified.

Clinton tells reporters at the Iowa State Fair on Saturday she was going to let the inquiry into her email use go forward. Clinton turned the server over to the FBI recently to investigate the security of her email setup.

Thousands of pages of her emails publicly released in recent months show Clinton did receive messages later marked classified, including some that contained material regarding the production and dissemination of U.S. intelligence.

Clinton's use of a homemade server during her time as secretary of state has dogged her campaign. She blamed her Republican challengers and GOP House members on Saturday for turning the affair into a partisan issue.
