Meanwhile, New York City Mayor Bill de Blasio Sunday condemned the violence in Charlottesville, Virginia, as "an act of domestic terrorism."

"It shouldn't be hard to say-what happened in Charlottesville was an act of domestic terrorism. Period," de Blasio tweeted.

"This white supremacy movement is a danger to us all, including our law enforcement officers who often engage with these hate groups," he said.

"New Yorkers know who we are-we are a city for everyone. We are particularly pained when we see violence carried out in the name of hate," he added.

A rally staged by white nationalists in Charlottesville turned violent Saturday. After hours brawls between the pro-rally far-right figures and anti-racism protesters, a sport car ploughed into crowd against the rally, killing a 32-year-old local woman and injuring 19.
