Thomas Jefferson wrote the famous words "all men are created equal," but he also owned more than 600 slaves over the course of his life.
His Virginia plantation called Monticello is being renovated to shed more light on the enslaved people who lived and worked there.
One of the most notable of those slaves was Sally Hemings. Jefferson is widely believed to have fathered her six children. The museum is working to restore a restroom believed to be Hemings' living quarters.
