Earlier in April, the bill was approved by the Oklahoma legislature. According to the document, health workers performing abortions may face up to 10 years in prison and a fine of up to $100,000.
"We want Oklahoma to be the most pro-life state in the country. We want to outlaw abortion in the state of Oklahoma", Stitt said at a signing ceremony on Tuesday with a video of the event later published on the governor's website.
Stitt said he believes that the bill would be challenged immediately by liberal activists, stressing the need to take a strong stand on the issue and protect unborn life in Oklahoma.
