I don't know if incompetence is all that simple of an explanation if you're trying to apply Occam's razor.
To get that AG job, you have to be incredibly politically and media savvy. These people conveniently becoming stupid when it comes to handling public perception and spin doesn't seem all that simple to me.
To me the simplest explanation is Trump spoke with a superficial knowledge of what was happening as usual. AG was like, "Cool. Let's release what we have." Someone from Trump's team reviewed the info to be released and saw it dripping with Trump references among references to other powerful people. Assistant goes back to Trump and says, "yeah, this is bad." Trump then says, "I'll instruct my lemmings to ignore it." Then BAM... an army of seafoams immediately stop caring about old men raping teens and lick those trump boots until they shine.
I guess Trump is involved so it's hard to have cohesive messaging when Trump is whipsawing his policy back and forth.
