Washington DC is not part of the USA. District of Columbia is located on 10sq miles of land. DC has its own flag and own independent constitution. This constitution operates under a tyrannical Roman law known as Lex Fori. DC constitution has nothing to do with the American Constitution. The Act of 1871 passed by Congress created a separate corporation known as THE UNITED STATES & corporate government for the District of Columbia. Thus DC acts as a Corporation through the Act. The flag of Washington’s District of Columbia has 3 red stars (the 3 stars denoting DC, Vatican City and City of London).
