Pauline Hanson and Greens Senator Sarah Hanson-Young have clashed on live television after the One Nation leader refused to condemn the far-right group that heckled Sam Dastyari last week.
Senator Hanson-Young asked why Senator Hanson refused to speak out against members of Patriot Blue for their verbal abuse towards the Labor senator at a Melbourne pub, labelling her as "irresponsible".
Senator Hanson hit back: "I just want to ask her [Hanson-Young], does she have to work at being a nasty piece of work or does this just come naturally?"
Senator Hanson later said she did not support the behaviour of the far-right group.
"I made it quite clear last week that no one deserves this. It is unacceptable. I think if Sarah had a look at what I copped for years: I had people throwing urine, tomatoes, eggs. I never heard one member of parliament stand up and support me," she said.
"It was not acceptable 20 years ago... it was absolutely disgusting. This is it, Sam [Dastyari] gets a few nasty words.
"You have called me time and time again a racist. You're a nasty piece of work Sarah Hanson-Young."
Senator Hanson-Young repeated her claim that Senator Hanson should condemn the group.
"We shouldn't see politicians giving cover for racists..." Senator Hanson-Young said.
Last week, Senator Hanson accused Senator Dastyari of using the incident to create publicity for his recently-released book.
"He's played up this whole thing," she told reporters on the campaign trail in Queensland.
"I've got absolutely no time for him whatsoever - I think he's a smart arse."
Senator Dastyari was heckled by far-right activists last week, with the Patriot Blue group sharing footage of the incident on their Facebook page. Prime Minister Malcolm Turnbull and Opposition Leader Bill Shorten condemned their actions.
