Republican under fire for using ‘Voltaire’ quote actually coined by neo-Nazi

The Kentucky Republican congressman Thomas Massie was under familiar fire on Monday, after criticising Anthony Fauci with a quote attributed to Voltaire but actually coined by a white supremacist convicted on charges related to child abuse images.

"To learn who rules over you," the quote says, "simply find out who you are not allowed to criticise."

Massie posted it to Twitter on Sunday, saying: "You mustn't question Fauci, for he is science."

Joe Biden's chief medical adviser is the target of rightwing criticism and death threats for his role in the US government response to Covid-19.

Massie is an energetic rightwing gadfly who last month issued a Christmas card image in which he and his family toted assault rifles.

Speaking to the Guardian then, Elaine Kamarck, a former official in the Clinton administration, said: "The guy's abominable but that's what's happening to the Republican party. They're flat-out nuts. There's a piece of the Republican party that now supports violence."

Larry Jacobs, director of the Center for the Study of Politics and Governance at the University of Minnesota, said: "We're into the kind of outrage culture in the Republican party. There's almost a competition as to who can be more outrageous, more vicious and threatening. It's a race to the bottom."
