Oklahoma hit a single-day record for cases on Wednesday, with 1,075, and the state’s governor, Kevin Stitt, announced that he had tested positive, becoming the first governor known to be infected with the coronavirus. Mr. Stitt, a Republican, has attended many public events and has often been photographed in public while not wearing a mask, including at an indoor rally for President Trump that was held in Tulsa, Okla., on June 20.
He said that he did not know where, when or how he had contracted the virus, and that his infection had not prompted him to second-guess his response to the outbreak.

Gov. Mike DeWine of Ohio, a Republican, gave an evening address on the virus in which he warned Ohioans that if they did not act to curb the recent uptick in cases, “Florida and Arizona will be our future.”
