I find it amusing that people believe that any of these news channels are even capable of anything investigative. They are talking heads. Period.
They rip news reports off the wires and re-write them (sometimes.). If you flip between the channels you will hear the same story, written the same way, using the same language. People doing that are not conducting deep investigations.
Expecting your favorite news reader to do anything more than reading the news and inject an occasional side comment is silly.
The ONLY people doing any news gathering are a bunch of producers working for peanuts—usually with a hangover. They are lazy and not really “aggressive.” This is true in every newsroom at that level.
They just aren’t news channels anymore. It’s pure entertainment industry pap wrapped around government mouthpiece propaganda and it’s been that way for a long time.
