CNN and (MS)NBC only ever aired one Trump speech.....when he got shot.

Title isn't completely true, and I can't take credit for it. But..... At some point CNN and NBC (including MSNBC) stopped airing any Trump speech or news conference because of disinformation. As best I can tell, this started around December 2023. After this policy was enacted, they had never aired a complete speech or press conference. Until the rally in PA where he got shot. What are the chances of this? Did they know?
