Houston Mayor Sylvester Turner said on Sunday that it is the time to draw a red line to keep the city from being divided by hate groups and anti-minority groups.
"Now is the time more than ever, now is the time, especially as leaders at our level to draw a red line," the mayor said in a TV speech.
"When it comes to Nazi groups, when it comes to the KKK, when it comes to the white supremacists and white nationalism ... we cannot be ambiguous," Turner said.
His remarks came a day after a 20-year-old man killed a woman and hurt 19 others as he rammed his car into counter protesters at a white nationalist rally near the University of Virginia.
On Sunday evening, hundreds of people attended a vigil in the Houston City Hall to support Virginia victims and to denounce the hatred expressed during the rally in the State of Virginia.
Thousands of white nationalists, neo-Confederates and right-wing protesters, as well as groups that oppose them, clashed on Sunday during the "Unite the Right" demonstrations that took place in Charlottesville, a historic college town in the state of Virginia bordering U.S. capital Washington D.C. .
