US supreme court is one, US court of appeals, and US district courts
One thing I learned from the video was that after purchasing land from Napoleon, Lewis and Clark were sent to explore the land and they were accompanied by a Native American woman named Sacajawea who served as a guide.
1776 was the year that the Americans declared independence from Britain. Aka, the Americans adoption of the Declaration of Independence. Guiding from that, a loyalist of Britain more than likely would more than likely not feel overly safe within America, hence they probably would've spoken I have to get on the next boat back to England.
Paying Indians. Hope this helps.
