My guess is Trump has another AG in mind, and is using Gaetz to gauge how in lock-step Republicans in the Senate are going to be with him. Gaetz probably won't have enough votes to get confirmed, and Trump realizes that, so he's got his true #1 option waiting to be recess appointed after Gaetz is shot down. Maybe Aileen Cannon? Or maybe he saves her for the Supreme Court. I dunno. But this acting AG will have two missions: Dismantle the federal investigations against Trump and punish Trump's enemies.
