OKLAHOMA CITY (KFOR) — A man climbed the Devon Tower in Oklahoma City Tuesday morning as an anti-abortion protest. Once he reached the top, though, he was met by first responders and police.

The climber’s name is Maison Des Champs and he is no stranger to climbing buildings. On his website —ProLifeSpiderMan.com — he says he even climbed the 600-foot Aria Hotel in 2021 to protest Nevada’s COVID-19 mandates.

According to Des Champs’ public relations firm, in the last month, he has scaled other skyscrapers in major U.S. cities, including the Salesforce Tower in San Francisco, as well as the New York Times building.

He didn’t use any climbing gear. Instead, he just used chalk for his hands as he scaled the 50-story building in downtown Oklahoma City.

Authorities were waiting for Des Champs at the top of the tower and took him into custody. He face possible charges of trespassing and disorderly conduct.

Meteorologist Emily Sutton says winds near the top of the building were around 35-40 mph at the time of Des Champs’ climb.

The Devon Tower has 50 floors and is the tallest building in Oklahoma.
