White House National Security Adviser Jake Sullivan has tested positive for COVID-19, the National Security Council announced on Saturday. 

"National Security Advisor Jake Sullivan tested positive today for COVID-19," NSC Spokesperson Adrienne Watson said in a statement. "He is asymptomatic and he has not been in close contact with the President."

Sullivan's positive test comes days after National Institute of Allergy and Infectious Diseases Director Dr. Anthony Fauci and Health Secretary Xavier Becerra tested positive for the coronavirus. 

On Thursday, White House Press Secretary Karine Jean-Pierre sparred with NBC reporter Peter Alexander on the timing of Biden's last coronavirus test.

"It’s a regular cadence. That’s what we do. We will share, per CDC, when he was a close contact, and he has not been a close contact. If he was a close contact, we will let you know," Jean-Pierre said when asked about Biden's recent testing schedule.

When pressed further about an exact date as per usual, she declined to answer, instead repeating that Biden gets tested weekly.

"So as soon as you go back there and find out the date, you’ll share it with us?" Alexander asked.

"I’m not saying that," she responded.

As Alexander continued to ask about the specific date, Jean-Pierre explained that the weekly testing is standard procedure for Biden as recommended by his doctor and only impacted by close contact.
