Congress has an implied power to do something not explicitly described in the constitution that is necessary to fulfill its other constitutional requirements. this power is based in the  necessary and proper clause.

Explanation:

The Necessary and Proper Clause is introduced in the Constitution of the United States in its Article I, Section 8. This clause establishes that Congress may sanction the laws necessary to be able to exercise its powers efficiently. That is, this clause removes rigidity from the Constitution, by establishing that those laws and procedures that are reasonable, proper and necessary cannot be classified as unconstitutional. For this reason, this clause is also called "Elastic Clause".
