A group is suing Tulsa Mayor G.T. Bynum and Tulsa Health Department Executive Director Bruce Dart, saying the city’s mask mandate is harmful to healthy people.

Optometrist Robert Zoellner, Clay Clark, Dr. James Meehan, MD, and other Tulsa-based business owners are asking the city to immediately repeal the mask mandate which was passed by city council last month.

The group alleges wearing masks is causing healthy people to become sick while trying to prevent the spread of a disease that is not a deadly threat to children and much of the public.

“On the OSHA website it states that employers shouldn’t make employees work in an environment where they have less than a 19.5 percent oxygen level,” said Clayton Clark, one of the plaintiffs.

“And the mandated masks cause employees to dip below a 19.5 percent oxygen level within 10 seconds of wearing a mask, so I don’t want to make my healthy employees sick.”
