Which legislative act did Jefferson end during his presidency?

During Thomas Jefferson's presidency, he chose to end the Alien and Sedition Acts, which had been enacted in 1798 under President John Adams. These acts were designed to strengthen national security during a time of potential war with France, but they also severely limited civil liberties, particularly the rights of immigrants and freedom of speech.

Jefferson, a proponent of individual rights and limited government, believed that these acts were a violation of the First Amendment rights. Once he took office in 1801, he sought to repeal the acts, reflecting his commitment to what he termed a more democratic government that prioritized civic freedoms. By allowing the acts to expire and not enforcing them, Jefferson played a critical role in restoring civil liberties and signaling a shift away from the Federalist policies of his predecessor. This action aligned with his broader vision of democracy and individual rights, making it a significant legislative change during his administration.
