When did Jefferson repeal the alien act?

Thomas Jefferson did not repeal the Alien Act, as it was part of the Alien and Sedition Acts enacted in 1798 during John Adams' presidency. However, Jefferson did work to eliminate its more controversial provisions when he became president in 1801. He focused on reducing the impact of these acts, particularly through the repeal of the Sedition Act in 1802, which limited free speech. The Alien Act effectively expired in 1800 and was not enforced by Jefferson's administration.
