Why was David Letterman at Iowa’s game vs USC on Saturday?

Caitlin Clark’s final game at Carver-Hawkeye Arena last March was a must-watch event that drew celebrities from all over.

The same can be said for Clark’s jersey retirement on Sunday.

Prior to tipoff at Carver-Hawkeye Arena for Iowa women’s basketball’s Big Ten showdown vs. No. 4 USC, comedian and former late-night talk show host David Letterman made his way into the arena to watch the Hawkeyes and Clark’s jersey retirement.

Behind 28 points from Villanova transfer Lucy Olsen, Letterman watched the Hawkeyes give the fourth-ranked Trojans just their second loss of the season while sitting courtside next to former Iowa coach Lisa Bluder.
