WASHINGTON, (Reuters) –U.S. President Joe Biden called for all Americans Tuesday to reject “poison” of white supremacy. He addressed families and officials at Buffalo, New York’s site of what police believe was a racially motivated massacre over the weekend.

White sumpremacy can be a deadly poison. It is poisonous, it truly is.

He said the white gunman who killed nine Black Americans and a white security guard trying to protect them was fueled by “hate that through the media and politics, the internet has radicalized angry alienated, lost and isolated individuals into falsely believing that they will be replaced …by the other. By people who don’t look like them.”
