US Vice President Mike Pence's press secretary has the coronavirus, the White House said on Friday, making her the second person who works at the White House complex known to test positive for the virus this week.
President Donald Trump, who publicly identified the affected Pence aide, said he was "not worried" about the virus spreading in the White House. Nonetheless, officials said they were stepping up safety protocols for the complex.
Pence spokeswoman Katie Miller, who tested positive on Friday, had been in recent contact with Pence but not with the president. She is married to Stephen Miller, a top Trump adviser. The White House had no immediate comment on whether Stephen Miller had been tested or if he was still working out of the White House.
Katie Miller had tested negative on Thursday, a day before her positive result.
"This is why the whole concept of tests are not necessarily great," Trump said. "The tests are perfect but something can happen between a test where it is good and then something happens."
