It's important to point out that many US politicians, beginning with President Jefferson in the early 1800s devised plans for the Federal Government to gradually phase out slavery, in part by purchasing freedom for slaves.
All such plans (none ever adopted) before the time of Lincoln's meeting with Black leaders in the White House, included provisions to return freed-slaves to Africa or the Caribbean.
Lincoln was the first President to recognize African-American wishes to remain in the US as citizens.
Lincoln supported colonization all his life; many people did. To say that Lincoln supported deportation at all, much less at the end of his life, is a gross exaggeration of the facts.
