Wrestlers from the United States, Iran, and Russia have appeared jointly at the United Nations to promote the value of wrestling.
The teams, which are in New York for a wrestling exhibition on May 15 at New York's Grand Central Station railway terminal, hope to apply pressure on the International Olympic Committee to keep their sport in the Olympics.
The International Olympic Committee's 15-member executive board sparked outcry in February when it voted to recommend that wrestling be dropped from the 2020 Olympic program.
The committee will make a final decision in Buenos Aires in September on which sport will get the final spot in a revamped lineup for 2020.
Wrestling is battling against baseball and softball, karate, rollersports, wushu martial arts, wakeboarding, squash, and climbing.
