"If you just sit for a moment and imagine those bullets going through those bodies, and what those bodies might have looked like afterwards, how can the president of the country talk about all the things he's going to do, and then go have lunch with the [National Rifle Association] and change it?" Popovich said at the time.

He also captured headlines after he called the United States a "global embarrassment" under Trump's leadership following his attacks on black athletes who have boycotted standing for the national anthem. 

Popovich's political statement also comes a week after Los Angeles Lakers player LeBron James donned a similar "Beto" hat shortly before his team's match-up against the San Antonio Spurs last Saturday.
