Those are speculative, and seem to be based on factual misunderstandings as to what’s actually happening. For example, there’s just one non-treasury employee with “over the shoulder” access to the system supervised by treasury employees: https://x.com/kyledcheney/status/1888904650906099774
People are going to make fools out of themselves again indulging every wild rumor and speculation (pee tape, etc.) without having the facts.
You asked specifically for a reference to what laws the team might be breaking, implying pretty clearly that you didn't believe any such reference could be produced; when it was, you moved the goalposts.
And you suppose the Trump administration can be trusted to supply those facts? Because that's the source you're citing, if I understand Kyle Cheney's tweet correctly (I may not!).
