>I can't prove that there was any White House advisory memo before the tariffs were announced, but hypothetically, would this not be considered material nonpublic information?
Was the hypothetical "White House advisory memo" produced using any proprietary information? If not, why should it be any different than if I hired a bunch of top lawyers to produce a private report for me?
Yes, because it was produced by the same people that are going to argue the case in court. You can hire the best lawyers in the world but they will still have to speculate on what arguments the government is going to make, and whether there are confidential communications showing evidence that there was some consistent rational justification for the tariffs and not just the president's public posts that leader X was mean to him on the phone so he imposed a tariff.
What a week argument - your still making excuses for this nonsense. Ridiculous.
Because this hypothetical memo was paid for by our tax dollars, not your own private money! That means it belongs to the American people, not individuals for their private gain. Using it for your own gain would be theft from the American public.
In this hypothetical case, of course. There is no evidence that such a memo exists. But if it did...
