the ABC's coverage of the 1991 Gulf War to be biased. In 1996, conservative Opposition Leader John Howard refused to have Kerry O'Brien of the ABC moderate the television debates with Labor Prime Minister Paul Keating because Howard saw O'Brien as biased against the Coalition. Liberal Prime Minister Tony Abbott perceived the ABC to be left wing and hostile to his government, while his successor Malcolm Turnbull enjoyed better relations with the national broadcaster. Specific topics The Catholic Church and George Pell The ABC's coverage of the issue of sexual abuse in the Catholic Church received praise and criticism. The Melbourne Press Club presented the 2016 Quill for Coverage of an Issue or Event for the report George Pell and Sexual Abuse in the Catholic Church, and the 2016 Golden Quill award to Louise Milligan and Andy Burns for their extensive coverage of Cardinal George Pell's evidence given at the Royal Commission into Institutional Responses to Child Sexual Abuse. The ABC Media Watch program of 20 April 2020 noted that the ABC had been accused of leading a "witch hunt" against Cardinal Pell. Media Watch reported that, following his acquittal, Pell said the ABC gave an "overwhelming presentation of one view and only one view". Media Watch also canvassed other criticisms including from The Australian newspaper's editor-at-large Paul Kelly, who charged the ABC with having run a "sustained campaign against Pell". Media Watch also offered criticism of its own, noting Louise Milligan and the Four Corners program had failed to canvass any of Pell's defence from the trial and "lined up witnesses condemning Pell", while social media commentary by Barrie Cassidy and Quentin Dempster had undermined the presumption of innocence. Margaret Simons similarly noted in The Guardian that "there has been some social media activity by ABC journalists that looks very much like lobbying against Pell..." Environmentalism Planet Slayer was an ABC website run by scientist Bernie Hobbs to teach children about the environment in around 2008/9. It included a "Greenhouse Calculator" which aimed to help children to work out their carbon footprint by providing an estimate of the age a person needs to die if they are not to use more than their fair share of the Earth's resources. Victorian Liberal senator Mitch Fifield criticised a cartoon series on the site for portraying those who eat meat, loggers, and workers in the nuclear industry as "evil". ABC managing director
