 Over the last couple of days, you've had a story up on your website about a Parkinson's expert who has been visiting the White House with the physician that is in charge of Joe Biden's health. The White House physician, I believe, is the official title. What can you tell us about this? How certain of it are you? What do you think, since we have not heard the White House, to my knowledge, comment on this? What do you think this is telling us? Kind of lay it out for the audience.
