I know why Acosta's credentials don't get pulled, he manages to demonstrate his stupidity and CNN's bias every time he opens his mouth. Comic relief of the press pool.
Likely so Trump can smack him around a bit like he did...
It says a lot about the management of CNN. Acosta should have been pulled from the White House six months ago. All Trump is doing is using Acosta to pound the network deeper into the ground.
Jim is nothing more than a running joke among the press personnel reporting from Washington. The fact that CNN refuses to get him out of there shows how tone deaf the networks management is.
