The last administration did not advocate buying a single company's stock. It did advocate for a certain direction for a particular industry (EVs for automotive) and in that context and in the context of passed legislation, highlighted many efforts of prominent American manufacturers, including GM and Ford. It did not specifically invite Tesla to the same event, and perhaps that was politically motivated, but I frankly don't see the exclusion of one market participant from a general promotional event as anywhere in the same universe as promoting the purchase a particular entity's stock. You're making a false equivalence and you know it.
I'll also add that promoting consumers to purchase goods from certain companies and promoting them to purchase STOCK is entirely different. The former at least is in the general ballpark of what the Department of Commerce is supposed to be doing. The latter isn't and looks more like a pump and dump effort than anything else.
