Rio de Janiero: The right-wing front-runner in Brazil's presidential race rejected support from supremacist groups after reportedly receiving praise from David Duke, a former Grand Wizard of the Ku Klux Klan.

"I reject any type of support coming from supremacist groups," Jair Bolsonaro wrote in English on his Twitter account. "I suggest that, for consistency, they support my adversary the candidate of the left party, who loves to segregate the society."

Duke, who endorsed US President Donald Trump in 2016, said on his radio show that Bolsonaro "sounds like us" and called him a strong candidate, a nationalist, and of European descent, according to a report published by BBC News Brasil and matched by other local media.
