Hope Hicks tested positive about 10 hours before Trump and Melania. So, someone else exposed Hicks and Trump and Melania likely all at the same time

Here's the situation. Trump and Melania and Hope Hicks were all likely exposed by the same person who likely didn't know that they were positive that traveled on the plane for four days with them around the U.S. So, the president, Hope Hicks and Melania likely were all exposed around Monday or Tuesday for this all to make sense medically.
