When George W. Bush ran for president, the presidency of George H.W. Bush was rarely brought up, though when Senator Chuck Hagel from Nebraska said that the younger Bush was tougher than his father, George W. Bush was upset – he felt that his father was not fair game. When the elder Bush tried to shoot a video about his son's life for the Republican party, he grew so emotional that he had to stop filming to gather himself. However, the senior and younger Bush worked together to make sure Barbara Bush, who is known for occasionally making tart remarks, didn't make any comments that would hurt the presidency. "It took a joint effort to keep her quiet," an adviser told Gibbs and Duffy. Bush the younger was the one who asked his father and Bill Clinton to work together on the relief effort for the Indian Ocean earthquake and tsunami in 2004, and George H.W. Bush and Clinton famously hit it off, often getting together socially.
