D.C. Attorney General Investigating Facebook Over Vaccine Misinformation

Facebook Inc. is under investigation by the attorney general for the District of Columbia over whether it has taken adequate steps to curb the spread of misinformation about vaccines. Attorney General Karl Racine is seeking internal documents that show how the social media giant penalizes users who violate its misinformation policies around vaccines, as well as materials related to a Facebook study about vaccine hesitancy among users, according to a copy of a subpoena issued by Racine’s office last month.
