OKLAHOMA CITY (AP) Oklahoma Gov. Kevin Stitt announced Wednesday that hes the first governor in the United States to test positive for the coronavirus and that he is isolating at home.

Stitt, 48, said he mostly feels fine, although he started feeling a little achy on Tuesday and sought a test. He said his wife and children were also tested Tuesday and that none of them has tested positive.

Stitt has backed one of the countrys most aggressive reopening plans, resisted any statewide mandate on masks and rarely wears one himself.

We respect peoples rights ... to not wear a mask, Stitt said during Wednesdays news conference, which was held virtually. You just open up a big can of worms.

Stitt attended President Donald Trump s rally in Tulsa last month, which health experts have said likely contributed to a surge in coronavirus cases there.

Stitt said hes confident he didnt contract the virus at the rally.

As far as where he became infected, its really unknown, Oklahoma Health Commissioner Lance Frye said. It wasnt so far back as the rally, which took place nearly a month ago.

There has been a dramatic increase in the number of people testing positive for COVID-19 in Oklahoma, with nearly 22,000 confirmed cases and 428 deaths.

One of Stitts cabinet members, David Ostrowe, tested positive for the coronavirus in March.
