Kellyanne Conway, the former top White House adviser, said on Twitter Friday night that she had tested positive for the coronavirus, making her the latest person close to President Trump to have gotten sick this week.
Ms. Conway attended White House events announcing Mr. Trump’s nominee for the Supreme Court, Judge Amy Coney Barrett, last Saturday.
“Tonight I tested positive for COVID-19,” she posted on Twitter. “My symptoms are mild (light cough) and I’m feeling fine. I have begun a quarantine process in consultation with physicians. As always, my heart is with everyone affected by this global pandemic.”
Ms. Conway told associates that previous tests she had taken were negative.
Mr. Trump and the first lady tested positive for the virus early Friday morning.
Three reporters who were with the president that day have also tested positive, as well as the first lady, two senators and the president of the University of Notre Dame.
White House medical officials are focusing on the events related to Judge Barrett as a source of the infection spreading.
But Mr. Trump’s introduction of Judge Barrett in the Rose Garden was most likely not a “super-spreader” event.
In small and poorly ventilated rooms, a single infected person talking and mingling with others — especially if they are unmasked — can potentially infect dozens of people. Such a super-spreader event is highly unlikely to have occurred outdoors in the Rose Garden, but someone who was infected and did not have symptoms could still have transmitted the virus to others during indoor discussions inside the White House.
Another adviser, Hope Hicks, tested positive for the virus on Thursday, but she did not attend the Barrett event.
