Democratic presidential candidate Joe Biden on Sunday toured the site of one of the protests that ripped through U.S. cities overnight and called for protesters against police brutality not to turn to violence.
Biden, wearing a face mask, made his second appearance outside his Delaware home since the coronavirus crisis hit in March, visiting an area in Wilmington where demonstrators vented outrage at the death of a black man shown on video gasping for breath as a white Minneapolis policeman knelt on his neck.
