Here's an overview AND TRANSCRIPTS of the three major networks' coverage of Trump's clashes with Bet O'Rourke and other Dems, in each case, the networks selectively omit the vicious attacks on Trump, and portray Trump's twwitter-post reaction as if it was the cataalyst, rather than the reaction to Democrats' incendiary rhetoric:

They don't factcheck Beto O'Rourke and other Dems' comments about Trump being a "racist" and "white nationalist", or cite ANY supporting facts, or cite the lack of facts supporting the allegation, they just report Beto O'Rourke's quoted words matter-of-factly as if they were true.
And in doing so, these "news" shows are part of the liberal Newspeak propaganda war, to front the Dems' lying talking points.

I would not be surprised if the networks had communicated by e-mail or phone conference directly with Democrat political leaders to coordinate these attacks. As with the Wikileaks-exposed Hillary Clinton and DNC e-mails in 2016, and with journo-list and other examples in elections before that, there is a collaborative Democrat/liberal media history of that occurring. Which is illegal, by the way.
