They also didn’t live stream the Butler PA rally either. You can check yourself. Search on YouTube or check the archive. There’s no stream that was specifically for that rally. Obviously as you pointed out they showed some clips from their reporter that travels with Trump as the rally happened live because he was the presidential nominee but that’s it.
