Since my [letter of October 28th], 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.What does it mean? It at least means that Comey stands by his recommendation that Hillary Clinton should not be prosecuted over the way she handled classified information. I can't see that it means Comey thinks he did wrong in sending that letter on October 28th or that there are no ongoing investigations involving Clinton. It says nothing — as far as I can tell — about investigations into the Clinton Foundation or the usefulness of the new email in that regard.
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.
Here's how the NYT puts it:
While the new letter was clear as it related to Mrs. Clinton, Mr. Comey’s message was otherwise vague. He did not say that agents had completed their review of the emails, or that they were abandoning the matter in regard to her aides. But federal law enforcement officials said that they considered the review of emails related to Mrs. Clinton’s server complete, and that Mr. Comey’s letter was intended to convey that.The NYT doesn't mention the Clinton Foundation. CBS News gives us this statement from Republican National Committee Chairman Reince Priebus:
"None of this changes the fact that the FBI continues to investigate the Clinton Foundation for corruption involving her tenure as secretary of state.”
