President Donald Trump has signed an executive order formalizing his announcement earlier this week that he’ll freeze assistance to South Africa for a law aiming to address some of the wrongs of South Africa’s racist apartheid era.

The president ordered that all foreign assistance to South Africa be halted and said his administration would prioritize the resettling of white “Afrikaner refugees” into the United States.

Trump and his allies have targeted South Africa, promoting the false narrative that white people are being mistreated by the nation’s post-apartheid government.
