But none of that indicates that Horowitz is a joke, or that he’s politically motivated - I commented more extensively above, but he seems like a pretty by the book/down the line civil servant.

What IS likely political is that someone was clearly keeping a very close eye on Rollins’s comings and goings, and reporting any hint of impropriety to his office. He doesn’t have much option but to follow up on that stuff - it’s clearly petty bullshit, but ignoring it would be a political call.
