U.S. Sen. Brian Schatz says he has tested positive for COVID-19.

“Earlier this week, I tested positive with a breakthrough case of COVID-19,” he said in statement issued today. “Thankfully, I am fully vaccinated, boosted, and asymptomatic. I have been following CDC guidelines and isolating at home. I am in consultation with the Office of the Attending Physician, and expect to be back soon.”

He is the second member of Hawaii’s congressional delegation to contract COVID-19.

U.S. Rep. Kai Kahele, who is also fully vaccinated and had received a booster shot, posted on social media on Dec. 26 that he experienced mild symptoms after testing positive for COVID-19. In the post, Kahele said he is “grateful for the protection provided against serious illness that comes from being vaxxed & boosted.”
