The Centre for Democracy and Technology, an internet-privacy watchdog, filed the first lawsuit against Donald Trump’s executive order seeking to strip social-media firms of liability protections for content posted on their platforms. The courts will probably rule eventually that the president does not have the authority to proclaim such a law, though federal agencies may try to implement it in the meantime. Mr Trump issued the order in a spat with Twitter over its policing of his tweets. It labelled one of his posts as “glorifying violence” the day after he pronounced his edict. See article.
