Miller’s positive diagnosis for Covid-19 puts the potential threat of the infection squarely into the president’s inner circle. Miller serves as the vice president’s top spokesperson, traveling with him frequently and attending meetings by his side. She is also married to another top White House aide and senior adviser, Stephen Miller, who writes the majority of Trump’s speeches and spends copious amounts of time around the president, Jared Kushner and Ivanka Trump.

Katie Miller’s positive diagnosis raises the risk that, through both her and her husband’s daily work, a large swath of the West Wing’s senior aides may also have been exposed to the novel coronavirus. She did not immediately respond to a request for comment.

“She’s a wonderful young woman, Katie, she tested very good for a long period of time,” President Donald Trump said on Friday during a meeting with congressional Republicans at the White House. “And then all of the sudden today she tested positive. She hasn’t come into contact with me. She’s spent some time with the vice president.”
