US President Donald Trump is often quick to respond to terrorising acts of violence.
As news broke of a terrorist attack in Paris in November 2015, Trump immediately tweeted that he was praying for "the victims and hostages". Very soon after a shooting at an Orlando, Florida, nightclub in June 2016, Trump tweeted that he was "right on radical Islamic terrorism".
But he kept quiet as a protest led by white nationalists, who arrived with torches and chants in Charlottesville, Virginia, on Saturday, turned violent. The cable networks that he usually watches showed footage of increasingly violent clashes between the white nationalists, some of whom looked like soldiers because they were so heavily armed, and the counterprotesters who showed up to challenge them.
He kept quiet as David Duke, the former leader of the Ku Klux Klan, declared that the scene in Charlottesville is a "turning point" for a movement that aims to "fulfill the promises of Donald Trump". The President kept quiet as Virginia Governor Terry McAuliffe (D) declared a state of emergency.
