Shortly after the American Civil War, as the states were rebuilding, a 2nd United States was formed. The District of Columbia became incorporated by Legislative Act in 1871 under the Emergency War Powers Act and the Reconstruction Acts. The name of this corporation is "UNITED STATES" which stands in distinction to the original United States of America. One is a sovereign Republic under a constitution, the other is a corporation built around Democracy.
This is why some people will say the UNITED STATES government is able to sidestep the Constitution and do things that it shouldn't be allowed to do. The UNITED STATES follows a different constitution than the United States of America. One uses lawful money, the other uses legal tender; one has sovereigns, the other has citizens; one has electors, the other has voters; one has a trial by jury, the other has a jury trial; one has lawyers, the other has attorneys. And the list goes on and on.
