In the 1990s, Gorton quietly rejoined the Liberal Party; John Hewson credited himself with "returning Gorton to the fold." In 1993, Gorton was invited to open the Liberal Party's campaign headquarters for the 1993 election. He endorsed Hewson's Fightback! package. In his old age he was rehabilitated by the Liberals; his 90th birthday party was attended by Prime Minister John Howard who said at the event: "He (Gorton) was a person who above everything else was first, second and last an Australian." Although he was back within Liberal circles, he never forgave Fraser; as late as 2002 he told his biographer Ian Hancock that he still could not tolerate being in the same room as Fraser.
