Ohio Gov. Mike DeWine tested negative for coronavirus on Thursday, hours after another test earlier in the day indicated a positive result.
A statement from his office confirmed the new result, reports Associated Press.
The results came from a different type of test that DeWine took in Columbus, considered to be more accurate than the quicker test he took earlier on Thursday.
His wife Fran DeWine, as well as staff members, also tested negative in Columbus.
The incident highlighted issues surrounding tests for the virus, including the fact that many citizens have to wait weeks for accurate results, as opposed to the hours that it took DeWine to get his.
DeWine first tested positive for COVID-19 ahead of a planned visit Thursday from President Trump in Cleveland, his office announced Thursday afternoon.
The Republican lawmaker's office said he took the test as part of standard protocol before meeting Trump at an airport in Cleveland.
DeWine had planned to join the president on a visit to the Whirlpool Corp. plant in northwest Ohio.
"A very good friend of mine just tested positive," Trump told reporters upon arrival in Ohio. "We want to wish him the best. He’ll be fine."
He is the second governor known to have contracted coronavirus, after Oklahoma Gov. Kevin Stitt, another Republican.
DeWine, 73, has no symptoms.
His office had said the governor will quarantine at his home for 14 days.
