Hillary Clinton Won't Face Charges For New Emails, FBI Director Tells Congress

An FBI investigation into newly discovered emails potentially pertaining to Hillary Clinton's private email server will not result in any new charges, the bureau announced on Sunday.

In a letter to Congress, FBI Director James Comey said that he was not going to revisit his prior conclusion that Clinton acted legally ― albeit carelessly ― in using a private account while she was secretary of state.

Since my letter, the FBI investigative team has been working around the clock to process and review a large volume of emails from a device obtained in connection with an unrelated criminal investigation. During that process we reviewed all of the communications that were to or from Hillary Clinton while she was Secretary of State. Based on our review, we have not changed our conclusions that we expressed in July with respect to Secretary Clinton. I am very grateful to the professionals at the FBI for doing an extraordinary amount of high-quality work in a short period of time.

The announcement comes a bit more than a week after Comey upended the presidential campaign by announcing that the FBI had discovered additional emails that were potentially pertinent to Clinton's server.

The letter Comey sent to Congress on Oct. 28 was vague. But subsequent reports revealed that the emails had been discovered on the computer of former Rep. Anthony Weiner (D-N.Y.), the estranged husband of longtime Clinton aide Huma Abedin.

Agents began poring through the newly discovered emails, which were believed to be roughly 650,000. Without knowing the results, Donald Trump and his surrogates have asserted that there would undoubtedly be confidential communications found among the emails. They have also argued that an indictment against Clinton was surely in offing, and have put out television advertisements based on the new discoveries

Sunday's announcement suggests, quite strongly, that is not the case. It was met with muted celebration from the Clinton campaign.
