Investigative journalists are reporters who dig deep into stories to uncover hidden truths. They often focus on issues like corruption, crime, and social injustices, using research, interviews, and public records to gather information. Their work aims to inform the public and hold powerful individuals or organizations accountable. These journalists play a crucial role in democracy by shining a light on important issues that may otherwise go unnoticed. They often face challenges, including legal threats and pressure from those they investigate. Notable examples of investigative journalism include the work of The Washington Post on the Watergate scandal and ProPublica's investigations into various social issues.
