I think it’s because when Trump worded things, he said there should be a disinfectant used to combat the virus. The media/Twitter immediately jumped to conclusions that he meant using Tide Pods and Clorox injected into the body, because that was the word association they had with “disinfectant”. Trump could have worded it a bit better, but considering he was on the spot and trying to explain a medical procedure (without a medial background) it was bound to happen. The media is being far more exceptional about this by not bothering to gather the full context, but that’s to be expected.
