Civil rights group and staff of Facebook are angry at Mark Zuckerberg claiming he is setting a “dangerous precedent” by allowing a post by Donald Trump to remain on Facebook.
The president posted “send in the National Guard”, and warned that “when the looting starts, the shooting starts”.
The anger underscores the US president’s post, about the widespread protests following the death of George Floyd.
The post was hidden by Twitter last week for “glorifying violence”.
Members of staff of Facebook ventilated their grievances at their employer, with some staging a “virtual walkout”.
When the message was shared on Twitter, it was hidden behind a warning label and it prompted an escalating squabble between Twitter and the White House.
After meeting Mr Zuckerberg, three civil rights leaders responded that he was wrong.
