New Hampshire Gov. Chris Sununu was diagnosed with a bleeding ulcer Friday, an aide said, after being admitted to a hospital in Portsmouth for tests on flu-like symptoms he'd been experiencing.
Sununu was still feeling flu-like symptoms Friday after several days, and had tested negative for COVID-19 three times earlier in the week, according to his chief of staff, Jayne Millerick.
She said Friday morning that he went to Portsmouth Hospital to be evaluated “as a precautionary measure to determine the cause of the flu-like symptoms he has been experiencing this week.”
Later Friday, she announced that Sununu was admitted to the hospital "for additional testing." The testing found that "a bleeding ulcer caused the symptoms the Governor has been experiencing this week," she said in a statement.

Sununu received a blood transfusion, Millerick said, and "is doing much better. He is extremely grateful to the staff at Portsmouth Hospital for their outstanding care and to everyone who donates blood. As a blood donor himself he is happy he paid it forward and grateful to all who do the same."
The statement didn't say whether Sununu had been discharged from the hospital, but it included a picture of Sununu in a hospital bed wearing a Patriots mask and giving a thumbs up.
Sununu had said Wednesday he tested negative for COVID-19, hours after his office said he wasn’t feeling well, postponed an Executive Council meeting and began isolating.
“I woke up with symptoms similar to COVID and out of an abundance of caution I took two rapid antigen tests, which came back negative, and then followed up with a PCR test, which confirmed the negative,” Sununu had said. “I am going to rest up, and look forward to getting back to the State House soon!”
Sununu is fully vaccinated against COVID-19. He received the Johnson & Johnson vaccine on April 10.
He took a trip to Kentucky on Monday to see how officials in that state are handling a surge in COVID cases.
