The United States Congress is the legislative branch of the federal government, in charge of sanctioning the federal laws that will govern life in society in the territory of the United States of America.
Congress is a bicameral organ, formed by two houses: the House of Representatives, which exercises a proportional representation of the population of each state; and the Senate, which represents each state of the country equally.
Due to this bicamerality, for a law to be sanctioned it must be approved by both chambers of Congress; that is, a double approval is required.
The President has the power to sign or veto legislation, command the armed forces, ask for the written opinion of their Cabinet, convene or adjourn Congress, grant reprieves and pardons, and receive ambassadors from other countries.
