Far-right Republican congresswoman, Trump ally and potential vice-presidential pick Marjorie Taylor Greene told a British interviewer to “Fuck off”, when asked about her frequent repetition of conspiracy theories.

Emily Maitlis, formerly a senior journalist at the BBC and now a presenter of the News Agents podcast, spoke to Greene at Donald Trump’s Super Tuesday celebration at Mar-a-Lago in Florida, as the former president closed in on the Republican nomination.

Raising a famous instance of the congresswoman’s eager conspiracy theorising, concerning what she thought was to blame for starting forest fires, Maitlis said: “What about Jewish space lasers? Tell us about Jewish space lasers.”

“No,” Greene said. “Why don’t you go talk about Jewish space lasers and really, why don’t you fuck off? How about that?”

“Thank you very much,” Maitlis said, as Greene walked away.
