But even with these explicit statements before him, the President appears to have been unable to form an opinion; and he referred the matter to the Attorney General, Hon. John Y. Mason, of Virginia, who had been bred a slaveholder, and fully sympathized with the slave power. He, having examined the whole subject, delivered a very elaborate opinion, embracing seven documentary pages;[132] but concluding with the opinion, that although the Exiles were entitled to their freedom, the Executive _could not interfere in any manner to protect them_, as stipulated by General Jessup, but must leave them to retire to their Towns in the Indian Territory, where _they had a right to remain_. [Sidenote: 1848.] We should be unfaithful to our pledged purpose, were we to omit certain important facts connected with this opinion of the Attorney General. Nathan Clifford, of Maine, was appointed Attorney General of the United States in 1846, soon after the report of General Arbuckle concerning the situation of the Exiles reached Washington. The subject was before the President more than two years. This delay we cannot account for, unless it were to save Mr. Clifford (being a Northern man) from the responsibility of deciding this question, involving important interests of the slaveholding portion of our Union. In 1848 Mr. Clifford was appointed Minister to Mexico, and Hon. Isaac Toucey, of Connecticut, was appointed Attorney General. But he, too, was from a free State, and it would throw upon him great responsibility were he constrained to act upon this subject. Were he to decide in favor of the Exiles, it might ruin his popularity at the South; and if against them, it would have an equally fatal effect at the North. Under these circumstances, recourse was had to an expedient. Before Mr. Toucey entered upon the discharge of his official duties, Mr. Mason, himself a slaveholder, was appointed to discharge the duties _ad interim_. He entered the office, wrote out the opinion referred to, and then resigned the office and emoluments to Mr. Toucey; having decided no other question, nor discharged any other duty, than this exercise of official influence for the enslavement of the Exiles.
