Six state treasurers are adding to the pressure for meaningful change at Activision Blizzard.

That's according to Axios, which reports that state treasurers from California, Massachusetts, Illinois, Oregon, Delaware and Nevada wrote a letter to the company asking for a meeting with its board of directors to “to discuss your response to the challenges and investment risk exposures that face Activision.”

The treasurers also said that they would be considering SOC Investment Group's call to "vote against re-election of incumbent directors."

“We think there needs to be sweeping changes made in the company,” said Illinois state treasurer Michael Frerichs.

“We're concerned that the current CEO and board directors don't have the skillset, nor the conviction to institute these sweeping changes needed to transform their culture, to restore trust with employees and shareholders and their partners.”

Massachusetts treasurer Deborah Goldberg added: “This particular case has been waiting for the board to step in and do an investigation. A true investigation, an outside investigator. And, I mean, what was it, two weeks ago that they said they stand by the CEO?”

A report in November revealed that CEO Robert Kotick knew about harassment and misconduct at Activision Blizzard and hid them from the board.
