Secretary of State Marco Rubio says South Africa’s ambassador to the United States “is no longer welcome” in the United States.

Ties between the United States and South Africa have deteriorated since Trump cut U.S. financial aid to the country.

Secretary of State Marco Rubio declared Friday evening on social media that South Africa’s ambassador to the U.S. was barred from entering the country. Rubio shared reporting from the far-right media outlet Breitbart News comments by Ambassador Embrahim Rasool linking President Donald Trump to White supremacy.
