Current Twitter CEO Elon Musk declared that Twitter will promote "reasoned" skepticism of scientific data.

"New Twitter policy is to follow the science, which necessarily includes reasoned questioning of the science," Musk wrote.

Musk also tweeted a statement that put Fauci's institutional accountability in question.

"Almost no one seems to realize that the head of bioethics at NIH – the person who is supposed to make sure that Fauci behaves ethically – is his wife," Musk wrote.
