US Supreme Court Justice Brett Kavanaugh on Thursday evening tested positive for COVID-19, according to a Supreme Court statement.

Per the court's regular testing protocols, Kavanaugh had a routine test ahead of Justice Amy Coney Barrett's investiture on Friday, said the statement.

He has no symptoms and has been fully vaccinated since January.

Kavanaugh, 56, has his last negative test that came Monday before the justices' in-person conference.

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

As a precaution, the Kavanaugh couple will not attend Justice Barrett's investiture on Friday morning, the statement added.
