Google has fired Margaret Mitchell, the founder and former co-lead on its ethical AI team, following an extended investigation that has kept Mitchell locked out of her corporate account since January.
It means both leaders on Google's ethical AI team now say they have been fired, leaving the future of the group unknown.
Mitchell announced the news on Twitter on Friday by simply writing "I'm fired."
In January, Google blocked Mitchell's corporate access for downloading and sharing emails related to Timnit Gebru, the AI ethicist — and other former ethical AI co-lead — who said she had been fired from Google last December.
"After conducting a review of this manager's conduct, we confirmed that there were multiple violations of our code of conduct, as well as of our security policies, which included the exfiltration of confidential business-sensitive documents and private data of other employees," a Google spokesperson told Insider on Friday.
Mitchell and her team were told that she had been fired at the same time, according to a Google employee who requested anonymity because they were unauthorized to speak to the press
The news comes just a day after Google reorganized its AI division, appointing engineering VP Marian Croak to oversee its work in responsible AI research.
On Friday, the company also said it had completed its investigation into Gebru's exit, and announced a series of new policies to increase staff retention and boost diversity and inclusion, Axios first reported.
Google may have hoped these moves would quell weeks of unrest in its AI division, but Mitchell's firing is likely to further rankle many employees.
"Three months ago Google had two ethics co-lead," tweeted Dr. Alex Hanna, a senior research scientist on the ethical AI team, following Mitchell's firing. "It has fired both and is running a smear campaign against them, to boot."
