A second White House worker — reportedly the vice president's spokeswoman — has tested positive for coronavirus, AFP reported officials as saying on Friday, even as President Donald Trump continued to go mask-free at a World War II commemoration with veterans in their 90s.

A senior administration official said a member of Vice President Mike Pence's staff had been tested and found to have coronavirus.

Trump, speaking later at an event with Republican lawmakers, identified the person as “Katie,” saying she works with Pence as a “press person”. This appeared to confirm multiple media reports that the person is Katie Miller, Pence's spokeswoman and the wife of Stephen Miller, one of Trump's most influential advisors — someone with frequent access to the Oval Office.

As recently as Thursday, Katie Miller was seen mingling with officials at an outdoor prayer ceremony hosted by Trump and attended by dozens of people, including the wives of Trump and Pence and many senior staff.
