Andrew Hastie has accepted an apology from his former colleague Barnaby Joyce over a One Nation cartoon video labelling the former SAS captain a traitor but reiterated that he believed Pauline Hanson was a “lying coward”.The apology has revealed a split between Joyce and his leader, as Hanson instead appeared to double down on the controversial animation on social media, thanking Hastie for drawing attention to the video posted more than one month ago and saying critics should “take a chill pill”.Hastie had called on Hanson and One Nation to take ownership of the cartoon or remove it from social media, after the One Nation leader said she personally had not called the Liberal frontbencher a traitor.The One Nation video posted to social media in late July depicts Hastie as a pitiful and paranoid opposition leader manipulated by Anthony Albanese into taking on One Nation.It also refers to him being a traitor after he gave evidence against the Victoria Cross-winner Ben Roberts-Smith in his failed defamation trial.Joyce quickly distanced himself from the video on Wednesday, saying he was not aware of it. He later told the press he had reached out to Hastie.On Friday Hastie told Guardian Australia he accepted Joyce’s explanation.“Barnaby Joyce has reached out to me and explained that he didn’t know about the cartoon that called me a traitor eight times,” Hastie said. “I accept his explanation.“I called him a lying coward because I thought he was protecting Pauline Hanson. I now know that she is the only lying coward.”
