Nation of Islam leader Louis Farrakhan trended on Twitter on Saturday after he accused Dr. Anthony Fauci and Bill Gates of trying to “depopulate the Earth” through the development of vaccines aimed at ending the coronavirus pandemic.

Speaking at Nation of Islam headquarters in Chicago, Farrakhan urged African leaders and his followers to avoid accepting vaccines and medications developed by Western scientists.

“I say to my brothers and sisters in Africa, if they come up with a vaccine, be careful. Don’t let them vaccinate you with their history of treachery through vaccines, through medication,” Farrakhan said during the speech, which he gives annually on the Fourth of July.

“Do not take their medication,” the 87-year-old firebrand continued.

This year’s speech drew particular attention after Fox Soul, a division of 21st Century Fox, came under fire for planning to stream the event online. Farrakhan has a history of making anti-Semitic remarks.

Farrakhan proposed convening a team of virologists and epidemiologists to inspect whatever vaccines are developed to deal with the coronavirus.
