Conservative political columnist Robert Novak has a brain tumor, although the lesion has yet to be biopsied for diagnosis. According to an article in the on-line New York Times , "Last week, while driving in Washington, Mr. Novak struck a pedestrian, who was not seriously hurt, and said later that he had not been aware he had hit anyone. It is not clear whether the brain tumor contributed to that accident." Thanks to the illustrious Dr. Ranleigh Fleshman for alerting me to this piece of news. I'll let you know what the diagnosis is once it is made public.
