The CFAA covers knowingly transmitting, retaining, or using information obtained through unauthorized access. Directly and knowingly receiving the information from Nick.....and not using the information for journalistic purposes would make any defense based on the first amendment or "journalism" unlikely to be successful.
The government is unlikely to bring such charges of the person isn't engaged in commercial gain with the information. BUT its certainly something that the government can and would use to threaten individuals into cooperation with an investigation.
The biggest danger any of these people face is in terms of what they say to any potential investigators that contact them. IF the FBI is investigating and IF the case is taken seriously, lying to the FBI about material issues is a good way to get a charge.
But again, any charges emerging from this is far from a certainty. But at the same time everyone directly involved in this would be a fool not to be very careful about everything they do and say.
