They also all participate in laundering of fake news. One of them throws up a totally false story and all of the others repeat it.
As a recent high-profile example, Washington Post falsely claimed that Trump told a Georgia election official to "find the votes", which a later leaked recording proved to be absolutely fabricated (they retracted it). CNN, MSNBC, BBC and other ethically bankrupt organisations printed the lie verbatim.
"CORRECTION: [...] Trump did not tell the investigator to “find the fraud” or say she would be “a national hero” if she did so."
That's a pretty whopping correction that changes the entire story. If he's asking her to investigate the votes to find wrongdoing, then there's absolutely no wrongdoing.
If that doesn’t tell you what the media is about I don’t what is. They literally ran with a story about the president they couldn’t corroborate and it turned out to be lies.
