Your posts prove I have not claimed that “Lincoln himself arranged. . .”
I hope that your misstating the facts is unintentional.
"Lincoln used..." If Lincoln used the slaves then he must have arranged for them.
In all honesty I've been having a bit of fun at your poorly-worded attempt at slandering Lincoln. I admit I did go out on a limb a bit by assuming you were referring to the Capitol Dome and not the Capitol itself because surely you knew that the Capitol itself was build 50 years before. But even with that your implication that Lincoln knew slaves were used on the construction still is idiotic. The work began in 1855, long before his inauguration. Were slaves used? Probably. But since work was commissioned long before Lincoln was president and since the work was done under the supervision of the Architect of the Capitol, Thomas Walter, then the Executive was in no way involved in planning, work, contracting, or hiring. Yet you continue to insist that Lincoln ordered slaves be used. Odd.
