(Reuters) – Oklahoma Governor Kevin Stitt announced on Wednesday that he had tested positive for the coronavirus, believed to be the first governor of a U.S. state to do so.

“I got tested yesterday for COVID-19 and the results came back positive,” Stitt said in a video conference call with reporters. “I feel fine, really, I mean you might say I’m asymptomatic or just slightly kind of a little bit achy.”

Stitt was one of the guests at President Donald Trump’s rally in Tulsa, Oklahoma on June 20.

The first-term Republican governor said he had worked with contact tracers on when his symptoms developed and they believed he would not have been contagious before Saturday.

Oklahoma is among a number of U.S. sunbelt states suffering a surge in COVID-19. On Wednesday, it reported a daily record increase in positive cases for the second day in a row, rising by 1,075 to over 22,000.

Stitt, 47, encourages Oklahomans to wear masks but rarely wears one in public and has not issued a statewide mask mandate.

He said he would be isolating away from his family and working from home until it was safe to “get back to normal.”
