An exposé is a journalistic piece that reveals hidden truths, often involving corruption, wrongdoing, or unethical behavior. It aims to inform the public and hold individuals or organizations accountable for their actions. Typically, an exposé is the result of thorough research and investigation, uncovering facts that may not be readily available. These reports can lead to significant changes in public policy or societal attitudes, making them a powerful tool in the realm of media and journalism.
