George W. Bush: I "wanted dad to be alive" to read biography

Washington (CNN) - Former President George W. Bush said Tuesday that he wanted to publish his personal biography about his father, former President George H.W. Bush, now because "I wanted Dad to be alive - to be able to see how much not only I care for him but a lot of people care for him."

"His presidency in many ways was overshadowed by his predecessor, and that's understandable," Bush said. "[But] people are beginning to reassess the presidency of 41 and I want to be a part of that process and I wanted him to know that process was going to take place."

Bush's comments came at an event with his father Tuesday marking the launch of the 43rd president's personal biography of the 41st president.

The discussion was moderated by former George W. Bush chief of staff Andy Card and held at the George H.W. Bush Presidential Library at Texas A&M University in College Station. It was a heartfelt tribute to the elder Bush, who left the White House 22 years ago and is now 90.
