More of Hillary Clinton's emails have been flagged for review for possible classified content.
FOX News Radio's Rachel Sutherland reports:
FOX News has learned more than 300 of the former Secretary of State's old emails are being scrutinized for possible classified content, with the potential for more as officials continue to screen the messages.
Clinton commented on the investigation at the Iowa State Fair...
(Clinton) "I'm going to let whatever this inquiry is go forward, and will await the outcome of it."
She also said again, that she had neither sent nor received emails marked classified through her personal email system.
