Every news channel reporting that the FBI is "reopening" their investigation into Hillary's emails. FBI, however, didn't use that language.

Legum:

The FBI, in other words, is not reexamining its previous findings. It is not questioning its previous legal conclusion that “no reasonable prosecutor” could determine that charges are warranted. Based on the letter, it appears that the FBI will simply provide the same scrutiny to these newly uncovered emails as it previously applied to the emails it already reviewed when it determined that criminal charges are not warranted.

Though the initial narrative to emerge from this new letter — a narrative pushed by Republican House Oversight Chair Jason Chaffetz — is that the FBI has “reopened” the case against Clinton, several reporters did acknowledge on Twitter that this narrative is not true.
