The United States Secret Service (which is often just called the Secret Service in the United States) is part of the United States government. Part of its job is to investigate when people make fake money. (Making fake money is called counterfeiting). However, the United States Secret Service is more well known for protecting important government leaders. Secret Service agents work as bodyguards and protect people like the President, Vice President, members of the United States Cabinet, people who are running for high office, and the family members of these people, and leaders from other countries who are visiting the United States. There are other people whom the Secret Service protects, too. A United States President would never be seen in public without Secret Service agents protecting him or her at all times.
