What does the elastic clause do?

The answer is in the 'necessary and proper clause' of the U.S. Constitution, better known as the 'elastic clause,' which allows Congress to make laws it needs to carry out its own powers.

Its a statement in the U.S. Constitution (Article I, Section 8) granting Congress the power to pass all laws necessary and proper for carrying out the enumerated list of powers.

Hope this helps :)
