"A true American leader both at war and in peace, President Bush was kind, heroic, thoughtful, and of the highest professional and personal character. He lived a life in service to his fellow Americans and taught those he touched with his unwavering integrity. Having known him personally, Tammy and I were honored to claim him -- as well as Barbara and other family members -- as a friend. In celebration of the 20th anniversary of the fall of the Berlin Wall in 2009, we had the singular opportunity to host the President and Barbara on what would be his final overseas trip. Highlighting his place as an honorary citizen of Berlin, I am proud to have had his portrait hung in the German Senate. Tammy and I send our condolences and prayers to the President's family -- his children, grandchildren, and great-grandchildren -- as well as the many friends sharing in his loss. We take comfort in knowing that, while we have lost him here on Earth, he has been reunited with Barbara and Robin in heaven. He leaves behind a legacy to which we should all aspire."
