In August 2018, U.S. President Donald Trump was accused of endorsing the conspiracy theory in a foreign policy tweet instructing Secretary of State Mike Pompeo to investigate South African "land and farm seizures and expropriations and the large scale killing of farmers",[28][29][30] claiming that the "South African government is now seizing land from white farmers".[31] The often critical narrative derived from farm attacks, and land reform, is an established subset theme of the broader conspiracy theory,[5] portrayed in media as a form of gateway or proxy issue to "white genocide" within the wider context of the Western world.[32][31] The topic in relation to South Africa and Zimbabwe is also simply used interchangeably with the subject,[33] as well as being used by white nationalists as a parabolic concept, or cautionary tale,[34] to justify policies to retain or increase white majorities in nation-states, or otherwise maintain their vision of white supremacy.[35][31] In July 2019, the US President was said to invoke the theory again, telling four non-white elected congresswomen of U.S. citizenship, to "go back" to their "broken and crime infested" countries.[10]
