There is a mindset that dominates academia and carries on into the media.
It is reflected in the political donations of journalists.
And the distribution of the story bias.
It perhaps one should say "stunning lack of anything resembling a distribution".
All news has bias, but some are more biased than others, and that bias varies from personal and ingrained to organizational and intentional. It's important to be able to separate the wheat from the chaff, as it were.
Project Veritas is a right-wing, extremely partisan organization with a shady history. They are not an organization that I would trust.
My awareness of him is from several "stunts" where he "went undercover" and interviewed his targets surreptitiously and then dishonestly edited the results to support his ideological narrative.
I associate cable news with general incompetence, corporate shilling and whatnot, but generally a "noisy" signal. PV, on the other hand, is driven purely by right-wing ideological goals.
You're wildly underestimating how rebellious newspaper editors are. If someone was messing with the reporting, everyone in DC would know, and you'd see remarkably detailed reporting on it throughout other parts of the press.
