In yet another dramatic encounter in the Oval Office, Donald Trump ambushed South Africa's president in a choreographed showdown on Wednesday.

But why is the president accusing South Africa of genocide?

On Trump100 US correspondents Mark Stone and Martha Kelner react to the US president's claims and Cyril Ramaphosa's response.

They debunk the far-right claims that thousands of white farmers are being killed in South Africa, despite what Mr Trump says.

Plus, we hear from an advocate for Afrikaners who says Trump may have been persuaded to welcome white South African refugees after speaking to his friends on the golf course.
