What is ONE power of the Federal government?
morpeh [17]

Answer:

The federal government is composed of three branches: legislative, executive, and judicial. Powers are vested in Congress, in the President, and the federal courts by the United States Constitution. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court. The government was formed in 1789, making the United States one of the world’s first, if not the first, modern national constitutional republic. It is based on the principle of federalism, where power is shared between the federal government and state governments. The powers of the federal government have generally expanded greatly since the Civil War. However, there have been periods of legislative branch dominance since then. Also, states’ rights proponents have succeeded in limiting federal power through legislative action, executive prerogative, or constitutional interpretation by the courts. A theoretical pillar of the United States Constitution is the idea of checks and balances between the powers and responsibilities of the three branches of American government
