During President Donald Trump’s campaign, he reserved special vitriol for NBC News correspondent Katy Tur, calling her “disgraceful”, “third-rate” and “not nice”. For 500 days, she followed him around the US to document and fact-check his volatile bid for presidency, becoming part of the first women-led politics team in the history of US network news. Katy joins ABC 7.30’s Leigh Sales to discuss her darkly comic campaign memoir, Unbelievable, and how she withstood the opprobrium of the most erratic presidential candidate in US history.
