I think the reps were afraid the judges would cave and release it
Sounds to me like this is going to be a fairly well publicized topic.
Hopefully, the reps will be forced to revisit their decision.
Possible, but not likely. There is some Republican who is dirty on this one (using IRS or Justice for personal investigation) and they probably don't want to feed the Pelosi machine any more fodder for the "party of corruption" crap. Just my guess.
