true

I am pretty sure that slaves did help build the white house, i am not sure where they lived, but i dont think they lived inside.

TRUE, slaves were an integral part of the construction of the U.S. Capitol building and grounds, “Slaves were the largest labor pool when Congress in 1790 decided to create a new national capital along the Potomac surrounded by the two slave-owning states of Maryland and Virginia,” according to the June 1, 2005, Associated Press article “Capitol Slave Labor Studied” published in The Washington Times. Slaves were also involved in the Capitol building’s expansion over 50 years later. The task force, led at the time by Sen. Blanche Lincoln (D-Arkansas), recommended by November 2007 that the great hall in the new Capitol Visitor Center, which just opened December 2, 2008, be named “Emancipation Hall” to recognize the contributions of the slaves. The name change became official on December 22, 2007 by Public Law 110-139. Senator Lincoln had long advocated for such recognition after pay stubs dating from the 1790s were discovered in 1999. The stubs authorized the Department of Treasury to pay slave owners $5 per month for each laborer.
