Ohio Gov. Mike DeWine tested negative for the coronavirus on Thursday, just hours after he had tested positive, according to a statement from the governor's office.
DeWine was originally tested before he was set to greet President Trump at the Cleveland airport. After testing positive, he instead returned to Columbus, where he was tested for a second time.
The second test was a PCR test, which his office said was "extremely sensitive, as well as specific, for the virus."
"The PCR tests for the Governor, First Lady, and staff were run twice," the governor's office said in a statement. "They came back negative the first time and came back negative when they were run on a second diagnostic platform."
The PCR test looks for the specific RNA for SARS-CoV-2, the virus that causes COVID-19.
DeWine's office said the test was different than the rapid antigen test given earlier that morning as standard protocol for those seeing Trump.
"We will be working with the manufacturer to have a better understanding of how the discrepancy between these two tests could have occurred," the office said.
The governor and his wife said they plan to have a second PCR test on Saturday to confirm the results.
