Trump Appoints Himself Emperor of All Commerce

From the Wall Street Journal:

President Trump said U.S. companies were “hereby ordered” to start looking for alternatives to doing business in China after Beijing said it would impose tariffs on $75 billion worth of additional U.S. products.
….Mr. Trump’s comments came in response to China’s plan, laid out Friday, to impose tariffs of 5% and 10% on almost all the remaining U.S. imports on which it has yet to impose punitive taxes, including vehicles and car parts, in retaliation against U.S. moves to slap punitive tariffs on an additional $300 billion of Chinese goods. The president demanded that U.S. companies “immediately start looking for an alternative to China, including bringing your companies HOME and making your products in the USA.”

Wait. I thought we had all agreed that nothing Trump tweets is actually an order or anything like it. It’s merely a manifestation of how Trump wants his base to perceive him. In this case, he apparently wants them to perceive him as Albert Speer or something.
Anyway, the president obviously doesn’t have the authority to order US companies to do anything, even if he does use a big word like “hereby.” Still, I assume Republicans will all be shocked and outraged by this megalomaniac attempt to interfere in the free market. Right?
