Internet giant Google has fired the male engineer at the center of an uproar in Silicon Valley over the past week after he authored an internal memo asserting there are biological causes behind gender inequality in the tech industry.

James Damore, the engineer who wrote the memo, confirmed his dismissal, saying Monday that he had been fired for "perpetuating gender stereotypes."

Damore said he was exploring all possible legal remedies, and that before being fired he had submitted a charge to the U.S. National Labor Relations Board (NLRB) accusing Google upper management of trying to shame him into silence.
