The University of Southern California canceled a gubernatorial debate scheduled for Tuesday following criticism over the exclusion of candidates of color from the event.

The debate was set to feature six candidates, all of whom are white. The selection methodology, designed by a USC professor, drew particular scrutiny for including a low-polling mayor while excluding candidates of color from the lineup.

University officials defended their candidate selection process, describing the methodology as "air tight." However, the backlash over the lack of diversity in the debate lineup ultimately led to the cancellation of the event.

The cancellation highlights ongoing concerns about representation and inclusion in political debates, particularly as California's diverse electorate prepares for the gubernatorial election. The state's population is majority non-white, making the exclusion of candidates of color from the debate stage particularly notable.

The university has not announced whether it plans to reschedule the debate with modified selection criteria or alternative arrangements to address the diversity concerns raised by critics.
