U.S. Supreme Court Justice Brett Kavanaugh has tested positive for COVID-19, according to a statement.

The news of the diagnosis was first reported by Steven Mazie of The Economist, who covers the high court.

Kavanaugh was informed of the diagnosis Thursday night after a routine test. He has been fully vaccinated since January and is currently experiencing no symptoms from the virus, according to the statement.

Kavanaugh’s wife and daughters are also fully vaccinated, and they tested negative on Thursday.

A test of all nine justices on Monday came back negative for each.

As a precaution, Kavanaugh will not be attending any proceedings on Friday, including a ceremonial swearing-in for Justice Amy Coney Barrett, who was confirmed in October 2020 following the death of Justice Ruth Bader Ginsburg.

Further details about Kavanaugh’s health were not immediately available.

The Supreme Court has been on its summer break since early July. The justices added five new cases to its calendar for the term that begins next week, among them a challenge to federal election law brought by Republican Sen. Ted Cruz of Texas, according to The Associated Press.

Kavanaugh was nominated by former President Donald Trump and has served on the Supreme Court since October 2018, filling the seat vacated by retiring justice Anthony Kennedy.
