The US Justice Department has implemented a new policy that restricts employees from posting on social media about their government work. The policy aims to prevent social media posts that could 'damage the efficiency' of the department. The directive comes after a wave of political appointees made posts supporting President Donald Trump and criticizing his opponents. The new policy is much broader than previous restrictions, prohibiting employees from including their department titles on social media and reposting official government information. Free-speech advocates argue that the policy could stifle employees' speech and be used to target those with differing political views.
