I watched that live. This is the actual context. It lasted about 15 seconds, they shut her down, she agreed and then the entire panel spent the next five hours trashing Trump, calling his response pathetic and demanding his removal.
I have no love for CNN; I know exactly what they are. And these kind of behaviors (especially by Dana Bash, who does this all the time but has become notably sensitized to critique over it and backs down very quickly now, not just this time but last time) should always be called out and disciplined. But context is important for a sense of a larger picture, otherwise people are going to spend their entire day online on social media seeing the worst possible things clipped, breathlessly retweeted, and thinking the media is apologizing for Trump and spinning this for him, that he's invincible, and that is absolutely incorrect. I know what the Beltway media is and have for many years. I also know he put a lot of their lives in danger two days ago and they are pissed. That is what matters to them right now. It is important to understand their current posture while remembering how venal they are.
