The two main mistakes that were made when reporting the Hilary Clinton email scandal were: not being accurate about the information that was provided and timeliness. The New York Times has a reputation in providing some of the best pieces to the public and its unfortunate that they were so focused on delivery that they were not careful in verifying information before releasing it. Another error that could have been rectified was how they handled updating the information. The information was simply edited but never announced that the information was not accurate.
In order to avoid these kind of errors, it is best in the future to take full responsibility of the accuracy and the sources used for their work. Not only it is dangerous for the public, but for the person the news is about; in this case Hilary Clinton. This kind of inaccuracy could have put a damper on her career. The error needed to be edited right away, instead they took almost 48 hours to do so.
