What did the Virginia and Kentucky resolution clam?

The Virginia and Kentucky Resolutions, authored by Thomas Jefferson and James Madison in 1798, claimed that states had the right to nullify federal laws deemed unconstitutional. They argued that the Alien and Sedition Acts violated the First Amendment, asserting that states could interpose themselves between the federal government and their citizens. This assertion of states' rights was a significant early challenge to federal authority and laid the groundwork for future debates over state versus federal power.
