I can racial find statements from every President up to Eisenhower. Can't find as many promoting slavery though. As for L'lle a Vache. There was more than one African colonization program. A lot of them the brainchild of American Blacks and all done with their willing compliance. Lincoln's on the ground advice was pretty bad on Lille A Vache...not much different from more modern times huh?...thing is when they found out what happen they pulled the people out.
