Now Comey saying he doesn't know if there is anything relevant in the emails.
What WHAT
That was in his original letter to Congress.
To sum it up (from what I've read):
1. There is an FBI investigation into Weiner.
2. There was emails between Huma and Weiner.
3. Some of those emails are pertinent to the investigation into Clinton's email server investigation.
4. The FBI doesn't know what those emails contain as yet, but would not have changed his assessment about the case.
I think the press is really about the fact that nobody really knows anything about about anything at this point.
