White supremacists clashed with demonstrators who opposed racism and it ended in death and injury in Charlottesville.
The poll, conducted through and after Trump defended Tuesday his initial failure to specifically denounce neo-Nazi groups for their role in the attack, found rising disapproval of the president's response.
