WASHINGTON -- President Bush expressed sadness at the death of race car driver Dale Earnhardt and sent longtime friend and aide Joe Allbaugh to attend a memorial service Thursday.

"I am saddened by the untimely loss of this American legend and want to express my deepest sympathy to his family, friends and fans," Bush said in a statement.

"Dale was an American icon who made great contributions to his sport," the president said. "Dale's legacy will live on for millions of Americans. He was an inspiration to many."

Bush, who counted Earnhardt a friend, sent his condolences to Earnhardt's widow, Teresa, on Sunday, the day the seven-time Winston Cup champion was killed in the Daytona 500.
