Or is that what he wants them to put in the 4am talking points, before he blows them away with what else they signed?
If they wanted it to look like a political hit job, they will wait for October.
Because that is how you make it look political.
My guess is they don't want the appearance this is being timed for midterms. Plus it may not happen all at once. Its going to take time to unroll and arrest everyone involved, in a gradual redpilling. Arresting everyone at once also has horrible optics.
The other valid reason to delay is that they need/want to wait for Huber to indict anybody fingered in the IG report. Doing it the other way creates the appearance he's in diction from public pressure, or that the grand jury pool was tainted by the news or IG report.
