A Facebook spokesperson issued the following statement to The Intercept today: “No one has asked us to build a Muslim registry, and of course we would not do so.”

A group of 22 advocacy organizations issued letters yesterday (December 12) asking major techology companies not to assist Donald Trump’s incoming presidential administration with a proposed Muslim registry.

“Government targeting of individuals based on religion and ethnicity violates the Constitution and our core values as a country,” read the letters, signed by a coalition that includes CREDOMuslim AdvocatesColor of Change and Mijente

The group addressed the letters, which are uniform except in references to specific companies, to executives at Google, AppleFacebookIBM, Microsoft, Booz Allen Hamilton, CGI and SRA International. The list of targeting companies stems from an early-December article in The Intercept that asked those corporations and Twitter if they would ”sell any goods, services, information, or consulting of any kind to help facilitate the creation of a national Muslim registry, a project which has been floated tentatively by the president-elect’s transition team?” Only Twitter responded with a firm no. Microsoft said it wouldn’t ”talk about hypotheticals at this point,” and consulting firm Booz Allen Hamilton declined to comment. No other company responded to the public inquiry. 

“We believe it is a great sign of corporate responsibility and common decency for corporations to ensure their resources are not used to support bigotry and discrimination,” read the letters. ”An important first step would be for [company] to publicly refuse to help build a Muslim registry.”
