David Letterman worked as a reporter for ABC Sports during the 1971 race, and attended the race many times as a spectator. Since 2002, he has attended the race as co-owner of Rahal Letterman Racing. The team won the race in 2004 and 2020. At the 2015 race, Letterman was honored on the famous scoring pylon during the pre-race; just four days after he retired from the "Late Show".
