"Twitter sues US over anti-Trump account", 6 Apr 2017

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 rights of free speech afforded Twitter's users and Twitter itself under the First Amendment of the US Constitution include a right to disseminate such anonymous or pseudonymous political speech,” the company argued. It added that the government "may not compel Twitter to disclose information regarding the real identities of these users without first demonstrating that some criminal or civil offense has been committed"...In January, when Donald Trump became President Trump, several so-called "alternative" accounts for US government services began appearing online...According to the filing, the government sought to use a power given to the US Customs and Border Protection (CBP) - one typically used to obtain records relating to imported merchandise - to get detailed information on who was behind @ALT_USCIS.
