CNN has absolutely covered immigration issues and fentanyl overdoses. They didn't cover those subjects this week, because they had more important breaking news on the TV (like an unprecedented FBI raid on a former president) and those subjects had no new information to report. That doesn't seem relevant to you? Effectively FOX was covering that stuff because it needed filler material to suppress the stories it didn't want to run.
