A coalition of civil and digital liberties groups asked data brokers Monday to pledge that their wares will not be used in any potential tracking efforts by the government.
Groups ranging from the Columbia Law School Human Rights Clinic and Amnesty International to The Electronic Frontier Foundation and the Center for Democracy and Technology co-signed a letter to 50 brokers, asking that the companies that collect and co-mingle information to promise not to collaborate with any possible Muslim or immigrant registry proposed by President Trump.
