Twitter CEO Elon Musk said this week that the social media platform has a new policy on science that "includes reasoned questioning."
Musk tweeted on Wednesday: "New Twitter policy is to follow the science, which necessarily includes reasoned questioning of the science."
He later added, in response to a comment that mentioned Dr. Anthony Fauci the chief medical adviser to President Joe Biden, that "Anyone who says that questioning them is questioning science itself cannot be regarded as a scientist."
Musk previously ended Twitter's enforcement of its COVID-19 misinformation policy in November.
The billionaire previously claimed Twitter "actively suppressed" doctors and researchers during the COVID-19 pandemic.
