 George Stephanopoulos, in the interview last Friday, asked the president whether he has seen a neurologist. And the president said, no, no one ever told him he had to. And he says he undergoes a test every day, essentially, as president of the United States. He spoke figuratively. The idea that every day he has challenges that put him to the test. Right. These questions, however, are not going away. And the reporting now that, again, a senior neurologist from Walter Reed is in the visitor's logs eight times over the span of eight months raises questions.
