WASHINGTON (NewsNation Now) — South Carolina Republican Senator Lindsey Graham announced Monday that he has tested positive for COVID-19 despite being fully vaccinated.

He tweeted, “I started having flu-like symptoms Saturday night and went to the [House] doctor this morning.”

Graham added that he currently has mild symptoms and it feels like a “sinus infection.”

“I am very glad I was vaccinated because without vaccination I am certain I would not feel as well as I do now. My symptoms would be far worse,” Graham said.

Graham’s diagnosis comes amid a rise in cases among Congressional staffers and members. Florida Rep. Vern Buchanan had the first breakthrough case among a member of Congress in mid-July.
