can you show your work?
also please be careful not to conflate 'unreliable' and 'inconvenient to you'
While there are literally hundreds of examples from the past few years alone, I'll provide one for each side of the aisle, off the top of my head.
CNN's coverage of the Covington Kid. They claimed a crowd of teenagers surrounded a Native American elder and other activists and mocked them. They claimed Nick Sandmann was a racist. As someone who watched the entire few hours of video, long before CNN decided to base their "report" off of slanted tweets (which is what "journalism" is now) that's not what happened at all.
After the Black Hebrew Israelites, a group known for saying absolutely horrific things, taunted the Native Americans, they moved over to the crowd of high school kids and taunted them. Then the Native American elder
walked up to Nick Sandmann and proceeded to bang a drum and yell in his face. Nick stood there calmly and smiled, which was deemed a smirk. Sandmann has since sued, won, and settled.
Fox's coverage of SB 145. Their coverage implied the bill was to allow 24yr old pedophiles to have sex with minors as young as 14 without having to be registered as sex offenders. As someone who read the entire bill, that is not what it did at all. All it did was afford the same rights to gays that were already on the books for straight people. I'd get into more details but the intricacies of the topic are not to be discussed here.
I could go on all day about fake news, as I watch live streams of events in many cases, as opposed to listening to slanted takes on what someone has based on tweets they were forwarded. I also read documents, as opposed to listening to how someone personally feels about a document. The coverage of Trump alone, each individual thing he did or said, would provide pages of stories of how the MSM, especially left-leaning sources, fabricated, twisted, or blatantly lied about the facts of the matter.
