Liberal frontbencher Andrew Hastie says he will not back down from his criticism of Pauline Hanson, continuing to label the One Nation leader a lying coward. Mr Hastie says he has accepted Barnaby Joyce's apology, who was reportedly unaware of a One Nation cartoon describing the former veteran as a 'stupid traitor'. The Liberal frontbencher says Senator Hanson has not apologised, and he remains prepared to continue the fight with One Nation.
