Answer:
restricted the ability of the president to veto legislation.
Step-by-step explanation:
The Necessary and Proper Clause is an extension, not a restriction, of the powers specifically given to Congress. Clause 18 of Article 1 of the Constitution of the United States grants Congress the capacity to decide the governance systems and to enact proposed laws to enforce the specific powers set out in Clauses 1–17. It enabled the Congress to check the power of the president and thus works keep the principle of separation of power.
