Labor Senator Sam Dastyari has hit out at the One Nation Party after it questioned whether he had given up his dual citizenship before entering parliament.
"Dear One Nation, you're drunk, log off," the second-term senator said.
The Iran born Australian moved to Sydney when he was four years old.
It's not the first time Dastyari has sparred with One Nation.
He famously took the piss out of party leader Pauline Hanson on election night by inviting her for a halal snack pack to help celebrate her election to the Senate.
The pair also recently sparred on the ABC's Q&A, where Dastyari told Hanson exactly how he felt about her divisive policies.Suggest a correction
