Answer:
13 federal district courts, 3 circuit courts, and 1 Supreme Court
Explanation:
The Congress organizes the judiciary system with "13 federal district courts, 3 circuit courts, and 1 Supreme Court."
This is based on Article III of the United States Constitution which established a Supreme Court and enabled Congress the power to establish lower federal courts as required.
Hence, Congress established lower federal courts under the Judiciary Act of 1789, known as "An Act to Establish the Judicial Courts of the United States," which was passed into law under President George Washington on September 24, 1789.
This Act defined the structure and jurisdiction of the federal court system in the United States including the position of Attorney General.
