Federal authorities refer to the various agencies and departments of the national government that enforce laws and regulations across the country. These authorities operate under the jurisdiction of the federal government and are responsible for areas such as national security, immigration, and law enforcement. Examples include the Federal Bureau of Investigation (FBI) and the Department of Homeland Security (DHS). These agencies work to ensure public safety, uphold federal laws, and protect citizens' rights. They collaborate with state and local authorities to address issues that cross jurisdictional boundaries. Federal authorities play a crucial role in maintaining order and addressing crimes that affect the nation as a whole.
