ELI5: Explain Like I'm 5

Josh Wolf (journalist)

Okay kiddo, Josh Wolf is a journalist who went to jail because he wouldn't tell the government who he was getting information from. See, sometimes reporters need to keep their sources secret so they can keep getting information and keep people in power in check. But the government wanted to know who Josh's source was, and he said no. He spent a long time in jail for that, but he also became a hero for standing up for journalism and protecting sources.
