Secretary of State Marco Rubio has declared South Africa's ambassador to the U.S. as 'persona non grata' and no longer welcome in the country. This comes after the ambassador made remarks suggesting that President Donald Trump is leading a global White supremacist movement. Trump has previously criticized South Africa over a land expropriation law and issued an executive order penalizing the country. The South African government has claimed that the law will only be used to take land needed for public purposes and that there will be fair compensation.
