A more thorough explanation:

A public figure is someone who has become well-known to the public, either through their own actions or through their involvement in important events or controversies. According to the legal case Gertz v. Robert Welch, a public figure is someone who has taken on a prominent role in society or has inserted themselves into a public debate in order to influence its outcome.

Examples of public figures include:

• Politicians and government officials
• Celebrities and entertainers
• Athletes and sports stars
• Business leaders and entrepreneurs
• Activists and social reformers

Public figures are held to a higher standard when it comes to defamation and libel laws. In order to successfully sue for damages to their reputation, a public figure must prove that the person who made the defamatory statement did so with "actual malice." This means that the person knew the statement was false or made it with reckless disregard for the truth.

For example, if a newspaper publishes a story claiming that a politician took bribes, the politician would be considered a public figure and would have to prove that the newspaper acted with actual malice in order to win a defamation lawsuit. However, if the same story was published about an ordinary citizen who is not a public figure, they would only have to prove that the statement was false and caused them harm.
