Navajo Nation Speaker Seth Damon faces discipline by the Navajo Nation Council after an unflattering photo of him in a Las Vegas casino showed up on social media.

Damon was in Las Vegas earlier this month to attend the Indian National Finals Rodeo when he visited the casino. Someone took a photo of him slumped in front of a slot machine, appearing inebriated, and posted it online.

In a statement addressing what he called an “unauthorized photograph,” Damon said:

“Accountability and transparency are important leadership values I uphold as Speaker of the 24th Navajo Nation Council. Taking ownership is important to me.”
