However, about ten paragraphs in they mention:
> There is no indication that the White House was aware of the summons, which was signed by a Florida-based supervisor who works in an office that investigates employee corruption, misconduct and mismanagement. The supervisor could not be reached for comment."
So all we know at the moment is that some manager, somewhere in Florida, is looking into `ALT_uscis`. And yet, the article mentions Trump multiple times (including in the headline) before that, giving the impression that Trump is pursuing legal action that would seem to compromise freedom of speech. It's not unreasonable to infer that the journalists taking this angle on the story have an axe to grind.
Either way, I took a brief look at the `ALT_uscis` account and didn't see any tweets alluding to malfeasance or obstructive action in their official capacity, so I'm inclined to agree that this is government overreach.
