The State Department says South Africa’s ambassador to the United States, who was declared “persona non grata” last week, has until Friday to leave the country.

After Secretary of State Marco Rubio determined that Ambassador Ebrahim Rasool was no longer welcome in the U.S. and posted his decision Friday on social media, South African embassy staff were summoned to the State Department and given a formal diplomatic note explaining the decision, department spokesperson Tammy Bruce said.

She said Rasool’s diplomatic privileges and immunities expired Monday and that he would be required to leave the United States by Friday.

South African Foreign Ministry spokesperson Chrispin Phiri said in a television interview on Monday that Rasool was still in the U.S. but would be leaving as soon as possible.

Rubio announced his decision in a post on X as he was flying back to the United States from a Group of 7 foreign ministers meeting in Canada. In it, he accused Rasool of being a “race-baiting politician” who hates President Donald Trump. His post linked to a story by the conservative Breitbart news site about a talk Rasool gave earlier Friday in Johannesburg as part of a South African think tank’s webinar. Rasool, speaking by videoconference, talked about actions taken by the Trump administration in the context of a United States where white people soon would no longer be in the majority.

It is highly unusual for the U.S. to expel a foreign ambassador, although lower-ranking diplomats are more frequently targeted with persona non grata status.

Rubio’s decision was the latest Trump administration move targeting South Africa. Trump signed an executive order last month halting funding to the country. It criticized the Black-led South African government on multiple fronts, saying it is pursuing anti-white policies at home and supporting “bad actors” in the world like the Palestinian militant group Hamas and Iran.

South African President Cyril Ramaphosa told reporters on Monday that Rasool would give him a report when he returned home.

Ramaphosa said his government has “noted the displeasure that has been expressed by the United States,” and particularly about Rasool’s remarks, but stressed that he believed South Africa was in the process of rebuilding its relationship with the U.S.

“This is a hiccup, a hiccup we are working on straightening out,” he said.

“We will engage with the United States of America in a formal way,” Ramaphosa said. “We will do so with deep respect for them and for President Trump as well. Our relationship with the United States is going to be put on an even keel, so I would like the people of South Africa not to have sleepless nights.”

Bruce said the United States expects a certain level of respect.

“We’ve had a decent level of diplomacy with South Africa. There are some challenges, but you want people in each embassy who can actually facilitate a relationship,” she told reporters on Monday. “And these remarks were unacceptable to the United States, not just to the president, but to every American.”
