A more thorough explanation:

DOJ

The DOJ stands for the Department of Justice. It is a federal government agency responsible for enforcing the law and defending the interests of the United States according to the law.

One example of the DOJ's work is investigating and prosecuting cases of fraud, corruption, and other criminal activity. Another example is defending the United States in legal disputes, such as lawsuits filed against the government.

For instance, the DOJ may investigate a company for fraud if they suspect the company is deceiving customers or investors. The DOJ may also defend the United States in a lawsuit filed by another country or organization.

These examples illustrate how the DOJ works to uphold the law and protect the interests of the United States.
