Interesting answer on member of Congress’s postage privilege by acting Postmaster General Horatio King.

Post-office Department, January 28,1861.

Sir,—In answer to your letter of the 24th instant, asking if you have the right, “under existing relations,” to frank and distribute certain public documents, I have the honor to state that the theory of the administration is that the relations of South Carolina to the general Government have been in nothing changed by her recent act of secession; and this being so, you are of course entitled to the franking privilege until the first Monday in December next. If, however, as I learn is the case, you sincerely and decidedly entertain the conviction that by that act South Carolina ceased to be a member of the confederacy, and is now a foreign State, it will be for you to determine how far you can conscientiously avail yourself of a privilege the exercise of which assumes that your own conviction is erroneous, and plainly declares that South Carolina is still in the Union, and that you are still a member of the Congress of the United States.
