President Donald Trump said no US officials would attend this month’s Group of 20 summit in South Africa, the latest escalation in a rift that erupted over his claims that the country is mistreating White Afrikaners.

“It is a total disgrace that the G20 will be held in South Africa,” Trump wrote on social media, claiming that Afrikaners “are being killed and slaughtered, and their land and farms are being illegally confiscated. No U.S. Government Official will attend as long as these Human Rights abuses continue.”
