These are the people–employees of the “mainstream” network TV “news” shows–that got Trump elected, and he nevertheless blasts them because they belatedly started to do a perfunctory amount of actual vetting toward the end of the campaign. They still did the least amount possible to maintain the pretense that they are a legit news service.
As “DaisiesArePretty” writes at DailyKos:
“In spite of the hours and hours and hours of free media time they gave him — a 24/7 trump show … in spite of the hours and hours and hours of bashing Hillary over emails, bashing other Dems over hacked emails, to his advantage, then dropping the “important” email story as soon as trump won — (which Angela Marx talks about in this diary www.dailykos.com/…) … in spite of the short shrift the media gave to every candidate, in both parties, during the primaries … trump — shamelessly normalized by the media talking heads — called them on the carpet today and gave them a royal bashing. . . .”
And they actually stood there and took it. Their response is predictable: even more obsequious coverage of Fearless Leader.
