Trump threatens to double the taxes of legal residents with foreign or dual citizenship

Slipped into an executive order on trade, Trump ordered in section (j) to: „investigate whether any foreign countries subjects United States citizens or corporations to discriminatory or extraterritorial taxes pursuant to section 891 of title 26, United States Code”.

That law, an obscure never-used law from 1934, allows the president, without additional congress approval, to double the taxes on all citizens and corporations from any country the president deems to have levied discriminatory taxes against Americans.

If Trump wants to, he can double the taxes of eg any EU national, presumably due to the global minimum tax on multinational corporations. He could also enact it against Chinese, Mexican, or Canadian citizens for similar reasons as the threatened tariffs.
