The United States federal government operates through a system of checks and balances among three branches: the legislative, executive, and judicial. Congress, as the legislative body, creates laws and maintains accountability through its investigative powers. The President, serving as both head of state and leader of the executive branch, implements these laws with defined limitations. The judiciary, led by the Supreme Court, interprets laws and upholds constitutional meaning. This structured interaction fosters cooperation and ensures that power is neither centralized nor unchecked, preserving liberty and promoting governance for the common good.
