Can her mistake be accepted?

Tweet

Mrs. Clinton has used her personal email account on a private server at home that contained highly confidential information. Durin the Presidential Debate 1 she remarked that Mr. Donald is hiding something about his tax returns from the Government . He should place it. But, Donald coolly replied that if ready to release her private emails he will be the first to release the tax returns. Mrs. Clinton during the debate has finally conceded and stated that it was a mistake. How can such confidential information can be fed to a Private Server at home? Is there not something fishy.? The FBI investigation is on. The poor U.S citizen are listening to the debate with their mouths wide open. Of course, what can they do?
