What constitutional role does Congress play in the United States government?

Congress plays a vital constitutional role in the United States government primarily through the function of legislating. This involves crafting, debating, and enacting laws that govern the country. The Constitution establishes Congress as the legislative branch, consisting of two chambers: the House of Representatives and the Senate.

The legislative process enables Congress to address a wide array of national issues by proposing new laws, amending existing laws, and overseeing various governmental functions. This role is essential for maintaining a system of checks and balances within the government, allowing them to respond to the needs and concerns of the public effectively.

The description of other roles mentioned emphasizes their distinct functions. Executing laws is primarily the responsibility of the executive branch, which is led by the President. Judicial review, on the other hand, is a function of the judicial branch, particularly the Supreme Court, granting them the power to interpret laws and assess their constitutionality. Appointing ambassadors falls within the purview of the President, who can nominate individuals to serve in these positions, although such appointments require the Senate's approval. Each of these roles highlights the separation of powers that is foundational to the American political system, underscoring why legislating is specifically assigned to Congress.
