The thing is, the scope of the investigation has doubled. Garland and Smith have essentially rolled the January 6 failed coup (including the fake elector scheme) investigation into the Trump stealing state secrets and taking them to MAL. Meaning there are a LOT of pieces we don't see publicly put together and charges being drawn up for the guilty parties (hopefully all 41 members of Congress as well as Trump toadies like Roger Stone) in addition to the orange gasbag.
You hire a pit bull like Smith to charge criminals, not wind down a nothing burger investigation. I've said this before, Garland (by proxy Smith) has only ONE shot to nail FDJT. And I'm curious whether when Trump gets indicted, whether Congress critters like MTG and Gym get charged at the same time too.
