In the legislative branch, the U.S. Congress passes laws and appropriates spending for any fiscal policy measures. This process involves participation, deliberation, and approval from both the House of Representatives and the Senate.
The so-called Taxing and Spending Clause of the U.S. Constitution, Article I, Section 8, Clause 1, authorizes Congress to levy taxes.
