South African President Cyril Ramaphosa will visit the White House next week, his office said Thursday, days after the arrival in the U.S. of the first group of White South Africans, having been granted refugee status under a new Trump administration policy.

President Cyril Ramaphosa called the white South Africans “cowardly” for leaving for the United States. President Cyril Ramaphosa of South Africa said the white South Africans who left for the United States after being granted refugee status by President Trump were “cowardly,” as tensions mount between the two countries.

U.S. President Donald Trump’s claim this week that there is an unreported “genocide” happening against white farmers in South Africa was his harshest accusation yet against a country he has moved to punish over a range of issues.
