A US federal judge on Tuesday restricted some agencies and officials of the administration of Joe Biden from meeting and communicating with social media companies to moderate their content, according to a court filing.

The injunction came in response to a lawsuit brought by Republican attorneys general in Louisiana and Missouri, who alleged that US government officials went too far in efforts to encourage social media companies to address posts they worried could contribute to vaccine hesitancy during the height of the Covid-19 pandemic, or upend elections.
