Congress is the lawmaking branch of the United States federal government, and its main powers come from Article I of the Constitution. These powers matter because they shape national decisions about money, trade, defense, and public policy. The Constitution gives Congress specific enumerated powers while also setting limits so that no branch becomes too powerful.
Understanding these powers helps students see how laws connect to everyday life.
