Under the 1780 Pennsylvania statute, any adult slaves resident in the state for six consecutive months were automatically free. Three of Randolph’s own slaves had served notice that they planned to claim their freedom. Bizarrely, the attorney general of the United States urged the president and first lady to evade this local law. Coaching them how to do so, he noted that once slaves were taken out of Pennsylvania and then brought back, the clock was reset, and another six months needed to elapse before they could demand their freedom.
