WASHINGTON — Faiz Shakir, American Civil Liberties Union national political director, had the following reaction to the Department of Homeland Security’s notice on immigrants’ social media information:

“This Privacy Act notice makes clear that the government intends to retain the social media information of people who have immigrated to this country, singling out a huge group of people to maintain files on what they say. This would undoubtedly have a chilling effect on the free speech that’s expressed every day on social media. This collect-it-all approach is ineffective to protect national security and is one more example of the Trump administration’s anti-immigrant agenda.”
