Congress

Explanation:

The Constitution specifically grants Congress its most important power, the authority to make laws. A "Bill", or proposed law, only becomes a law after both the House of Representatives and the Senate have approved it in the same form. The two houses share other powers, many of which are listed in Article I, Section 8. These include the power to declare war, coin money, raise an army and navy, regulate commerce, establish rules of immigration and naturalization, and establish the federal courts and their jurisdictions.
