It is not the prerogative of the President of the United States to meddle with this matter, and Congress is not allowed, according to the Constitution, to legislate upon it. If Utah was admitted into the Union as a sovereign State, and we chose to introduce slavery here, it is not their business to meddle with it; and even if we treated our slaves in an oppressive manner, it is still none of their business and they ought not to meddle with it.
