U.S. Federal Agencies are specialized organizations within the federal government that carry out specific functions and responsibilities. They are established by Congress or the President to implement laws, provide services, and regulate various sectors. Examples include the Environmental Protection Agency (EPA), which focuses on environmental protection, and the Federal Bureau of Investigation (FBI), which handles national security and law enforcement. These agencies operate under the executive branch and are funded by taxpayer dollars. Each agency has its own budget, staff, and mission, allowing them to address diverse issues such as public health, education, and transportation. Their work is essential for maintaining order and providing services to the American public.
