The U.S. Congress passed a resolution late on Tuesday calling on President Donald Trump to condemn hate groups after Trump was criticized for his response to the violence at a white nationalist rally in Charlottesville, Virginia, a month ago.

The U.S. House of Representatives unanimously adopted the resolution, U.S. Representative Gerry Connolly, a Democrat from Virginia, said in a statement. The Senate approved the measure on Monday.

"Tonight, the House of Representatives spoke in one unified voice to unequivocally condemn the shameful and hate-filled acts of violence carried out by the KKK (Ku Klux Klan), white nationalists, white supremacists and neo-Nazis in Charlottesville," Connolly said.
