An early memo by former FBI Director James Comey accused Hillary Clinton of "gross negligence" in the handling of classified information, The Hill reported.
The statement concerns the investigation into Clinton using a private email server for official communications during her tenure as Secretary of State.
"There is evidence to support the conclusion that Secretary Clinton, and others, used the email server in a manner that was grossly negligent with respect to the handling of classified information," the early statement said, according to anonymous sources.
According to the report, the statement was then edited, with the specific phrase "grossly negligent" being replaced with the less incriminating definition of "extremely careless."
"The red-line history clearly shows the original statement was designed to allege Clinton committed gross negligence and then someone changed it to extreme carelessness. Clearly there was a difference of opinion on the term derived from the statute," one of the sources said.
The Hill reached out to both the FBI and Clinton for comment, but they’ve not yet responded.
Clinton used a private server for official business during her tenure as secretary of state from 2009 to 2013 contrary to US regulations and established practice.
The FBI conducted a criminal investigation into whether Clinton intended to violate US laws, but closed it and then reopened it again on account of new evidence just days before the November 8 election.
In both instances, former FBI Director James Comey recommended that the Justice Department do not criminally charge Clinton.
