Trump COVID-19 updates: Top Trump aide Stephen Miller tests positive

The vice president's office released a memo from White House physician Dr. Jesse Schonau that said Pence was tested for COVID-19, with a PCR test, Tuesday afternoon, and that his result was negative.

"Vice President Mike Pence is encouraged to go about his normal activities and does not need to quarantine," Schonau wrote.

Pence's office had told ABC News earlier that he and his wife Karen had tested negative Tuesday morning. This new memo was released after news broke that Stephen Miller, the husband of Pence's communications director Katie Miller, had tested positive.

It was unclear why the vice president was tested a second time.

Katie Miller was in Salt Lake City with the vice president, but has reportedly left the trip according to a pool report.

Rep. Salud Carbajal, D-Calif., has tested positive for COVID-19.

Carbajal said in a statement that he took a test upon learning he had contact with someone who tested positive for the virus. That initial test came back negative, and he began quarantining and self-monitoring for symptoms. After experiencing mild symptoms, he took another test Tuesday, which came back positive, he said.

According to his staff, Carbajal had been in contact with Utah Sen. Mike Lee, who tested positive for COVID-19 after attending the Supreme Court nomination ceremony at the White House Rose Garden on Sept. 26. Carbajal did not attend that event. 

In his statement, Carbajal said he will continue to work virtually. Staff members he interacted with have tested negative or are still pursuing testing.

"I hope this serves a reminder of how easily this virus can spread," he said. "I followed every precaution, including wearing a mask, social distancing and hand-washing and unfortunately was still exposed. It is incumbent on every single one of us to take careful precautions in order to protect the health and safety of those around us."

Since March, 125 Capitol Hill workers have tested positive for COVID-19, according to a House Administration Committee spokesperson. 

That number includes nearly 50 Capitol Police officers, according to the chairman and first vice-chairman of the Capitol Police union. Forty-three of those officers have since recovered. 

The union has been requesting mandatory testing for officers on the Capitol complex since March, but it has yet to be implemented.

Top Trump aide Stephen Miller has tested positive for the novel coronavirus.

He is married to the vice president's communications director, Katie Miller, who tested positive in May and was one of the first aides in the White House to contract the virus.

With the addition of Stephen Miller, it now means six out of the nine attendees in the Trump debate session from last Monday have tested positive.

“Over the last five days I have been working remotely and self-isolating, testing negative every day through yesterday," he said in a statement. "Today, I tested positive for COVID-19 and am in quarantine.”
