The Constitution establishes the legislative branch of the US government, known as Congress, which is made up of the Senate and House of Representatives. It outlines the composition and election process for both chambers, as well as their powers and responsibilities. These include the ability to create laws, approve the federal budget, declare war, and impeach and remove the president or other federal officials from office. The Constitution also establishes the basic framework for how legislation is passed and how the executive branch, through the president, can veto bills.
