It seems that the government is having a hard time with full transparency during the Discovery Documents period, hiding behind, Executive Privilege, National Security, ANYTHING THAT MIGHT STICK.
Here, I think "Negotiations", simply means negotiations over letting Plaintiffs have access to documents in the defendants possession!
With the government continuing its "sweep" of victories in almost every single court hearing to date, I don't think they are inclined to give in an inch on giving up one thin dime of the $308B transferred from the two private enterprises to the UST.
