San Fransico

Twitter is suing the US government after it demanded it reveal the identity of an anti-Trump account.

The @ALT_USCIS profile was an anonymous profile account criticising President Trump’s immigration policy.

The account claimed it was being run by federal employees at the United States Citizenship and Immigration Services.

Twitter has requested a court block the Trump administration’s request, calling it a matter of free speech.

The challenge was filed in San Francisco, where the micro-blogging service is based.
