Chances are, it's gonna be nothing more than a whole bunch of stuff that will embarrass, but not incriminate, Weiner or Huma.
Trump is just doing this to be petty and mean.
Really?
Trump is 'being petty' when a lawsuit leads to the release of emails? Did you even look at what was happening before making that comment?
As for the emails themselves, nothing new will be in them and there will be very little redaction. This was a massive non starter to begin with - the FBI has already DIRECTLY STATED there was nothing criminal in them.
(well further at least - Weiner's extra curricular activities excluded)
