Lincoln, Abraham, 1809-1865.
A. J. Grover, Esq Springfield, Ills.
My dear Sir: Jany. 15. 1860

Yours of the 9th. was duly received. In my joint debate with Douglas, at Freeport, Aug. 27. 1858, I said about all I have ever publicly said concerning the Fugitive slave law of 1850, and you can find it in print in the report of that debate. I said then in substance, and have often said, I think Congress has constitutional power to enact a Fugitive slave law; that the law of 1850 appears to me objectionable in some of its provisions; but whether it is unconstitutional in any of it's provisions, I do not remember that I have ever undertaken to decide. I should be glad to see you, and to talk with you more fully than I can write. Yours truly

A. LINCOLN
