Thomas Jefferson Tribes Quotations

For the power given to Congress by the Constitution does not extend to the internal regulation of the commerce of a State (that is to say, of the commerce between citizen and citizen,) which remain exclusively with its own legislature; but to its external commerce only, that is to say, its commerce with another State, or with foreign nations, or with the Indian tribes.

If ever we are constrained to lift the hatchet against any tribe, we will never lay it down till that tribe is exterminated, or driven beyond the Mississippi... in war, they will kill some of us; we shall destroy them all.
