Synthesis

The bill is constitutional under the Commerce Clause and Necessary and Proper Clause, but must be limited to projects directly affecting interstate commerce or federal property to avoid infringing on state powers.

Hamilton YES

This bill falls within the enumerated powers of Congress under the Commerce Clause, as the Mississippi River is a major artery of interstate and foreign commerce. Article I, Section 8, Clause 3 grants Congress authority to regulate commerce among the several states, and the protection and restoration of a navigable waterway that facilitates such commerce is a proper exercise of that power. Additionally, the Necessary and Proper Clause (Article I, Section 8, Clause 18) empowers Congress to enact laws that are necessary and proper for carrying into execution its enumerated powers, including the …

Article I, Section 8, Clause 3 Article I, Section 8, Clause 18 Federalist No. 23

The Mississippi River is a vital artery of interstate commerce, and projects that protect navigability and prevent obstructions fall within the commerce power. However, the bill's broad language of 'protection and restoration' could extend to purposes beyo…

Article I, Section 8, Clause 3 Tenth Amendment Federalist No. 45
Marshall YES

The Constitution entrusts Congress with the power to regulate commerce among the several states, and it is well settled that this power extends to the navigable waters of the United States, such as the Mississippi River. The proposed initiative to protect and restore the Mississippi River Corridor is a proper exercise of that commerce power, as the river is a vital artery of interstate trade and navigation. Under the necessary and proper clause, Congress may enact laws that are appropriate to carry into execution its enumerated powers, and the restoration and resilience measures are fitting me…
