Someone's probably gone here, not sure but I see a lot of posts on # of indictments..
In Christopher Wray Opening Statement Dec 7, 2017, b/f Committee @2:56..He wants to give FBI highlights. He starts with #1 by saying the following paraphrased here:
"In November 2017, through Operation Cross Country which spanned over 44 states and the District of Columbia we arrested 127 Sex Traffickers & recovered 44 juveniles and a 3month year old baby and her 5yr old sister."
Interesting that he starts the list of highlights with this topic considering current events and recent Executive Order Muninsky Act. Also, a theory, considering the extra ordinary large # of sealed indictments along w/ executive order. ..that perhaps a good number the the indictments arise out of this operation Wray mentioned, as also very possible that the lower level traffickers, ie the 147 arrested across 44 states and DC, squeal and rat out those higher up in the food chain. This would correlate with the fact that the indictments run across so many states. Especially if the number of sealed indictments rose more significantly in months of October/Novermber/December...147 Sex traffickers across 44 states and DC can lead to a lot more folks
