From what has been posted, it appears that they have given their presentment of an indictment to prosecutors. At this point, it's simply a presentment.
Now, if the prosecutor's decide to take action on that presentment (remains to be seen), then they will. If they don't take action...then the presentment remains just that...a presentment.
It's basically a criminal 'complaint' based on their notarized testimony and Grand Jury proceedings. What becomes of it is entirely up to the GA congresspeople and or the GA prosecutors.
There were citizen grand jury's formed regarding the 9/11 'truther' issues. However, no prosecutor took action on anything they did (so far as I know).
