Due to being in recess for August, I think a lot of the outrage you would see from Congressional Members is being muted. If this had happened in a couple of weeks I think we would have seen hellacious action coming from The Hill. Right now a lot of staff is either in the District office for their Member or if you work on a Committee on a staff del visiting something within your Committees jurisdiction so that might also be part of the reason for the muted response.

Back to your question as the revisions are being made she 100% knew that they were at least trending in a bad direction. I would expect her staff to have alerted her at certain thresholds of "wrongness". These types of revisions are not unheard of though. During Trump's time in office the did a revision election year about how they were 500k people high and at the time everyone made a huge deal out of it.

I have met Sec. Raimondo and all I can guess is that she was praying for some last-minute hail mary that would have helped lower the number. This number is generated by her staff so it is a little wild that she is somehow linking Trump to this. That would mean people have been in the Department for 4 plus years I guess just waiting around? It doesn't make any sort of logical sense.

This is also the person whose Government email was hacked by China for months so I guess nothing should really surprise me from her. Either way I am sure that once Members return we will see this brought up again. At a minimum you will see either the Ed and Workforce Committee or the Financial Services Committee fire off a letter demanding an explanation. There isn't really a way out for her from what I have seen because it wasn't like this data was dumped on her all at once it comes in phases so she knew or if she didn't I think that might be even worse that her staff isn't keeping her in the loop.
