The family of one of the participants in Saturday’s white supremacy rally in Charlottesville, Virginia, says they are disowning him.

Pete Tefft of Fargo, North Dakota, is one of the Charlottesville marchers whose photo was posted on @YesYoureRacist, a Twitter account that calls out racist behavior and attitudes.

In February, Tefft described himself to a reporter as “100 percent pro-white.”

Now, Tefft’s father says he and the rest of the family are 100 percent against his son’s racist beliefs.

In a letter published Monday in The Forum of Fargo-Moorhead, Pearce Tefft wrote that he and other family members ”wish to loudly repudiate” their son’s “vile, hateful and racist rhetoric and actions.”
