Final answer:
Section 5 of the Fourteenth Amendment gives Congress the power to enforce the amendment's provisions, including due process and equal protection clauses, by appropriate legislation.
Step-by-step explanation:
The part of the Fourteenth Amendment that gives Congress the power to enforce the amendment is found in Section 5, which states, "The Congress shall have power to enforce, by appropriate legislation, the provisions of this article." This specific clause grants Congress the authority to pass laws ensuring that the provisions of the Fourteenth Amendment are upheld, including its due process and equal protection clauses, and to address violations. For example, it has enabled Congress to pass civil rights legislation aimed at preventing or remedying discrimination and ensuring that states respect the civil liberties of all citizens.
