A prominent disinformation scholar who left Harvard University in August has accused the school of muzzling her speech and stifling—then dismantling—her research team as it launched a deep dive in late 2021 into a trove of Facebook files she considers the most important documents in internet history.

The actions impacting Joan Donovan’s work coincided with a $500 million donation to Harvard by a foundation run by Facebook founder Mark Zuckerberg and his wife Priscilla Chan. In a whistleblower disclosure made public Monday, Donovan seeks investigations into “inappropriate influence” from Harvard’s general counsel, the Massachusetts attorney general’s office and the US Department of Education.
