I am not about to jump into a debate about which of the two is "worse", because no matter the outcome it is absolutely disingenious to frame COVID-19 as "deadly coronavirus pandemic, which continues to wreak havoc on the lives and livelihoods of households across the country" in one context and plain "coronavirus pandemic" in the other. It is the same virus. If you don't see the bias in that then consider the possibility that you share it.
(Plus, Trump's rally was indoors; protests are outdoors. We've got quite a bit of data now indicating outdoor transmission is less likely.)
