What limitations are placed on Congress in terms of its powers and authority?

Congress is limited in its powers and authority by the Constitution, which outlines specific responsibilities and restrictions for the legislative branch. These limitations include the requirement to follow the principles of federalism, separation of powers, and checks and balances. Congress cannot pass laws that violate the Constitution or infringe on individual rights protected by the Bill of Rights. Additionally, the President has the power to veto legislation passed by Congress, and the Supreme Court can declare laws unconstitutional.
