Fake. The federal government is not a corporation.
This gets passed around but the truth is that all cities and most towns are incorporated under state law. This is context for the laws that are cited making the false claim that the federal government was taken over.
The law refering to the corporation is for the incorporation of washington DC as a city under federal law. Nothing more. Its federal law creating a federal corporation because dc is federal.
Law taken out of context to spin fantasy
