When Donald Trump denies sexual assault notice his tells of lying immediately after he utters vital words such as ”lie”, ”false” etc…. Observe how he looks away from his audience just after he makes the the denial.
Contrast this with the testimony of his accusers. Summer looked straight at the camera unblinkingly as she spoke the words. Mark well her candour.
I would that Donald Trump was subjected to a polygraph test. He cannot be compelled to do so but he can be invited to undergo such a test. If he refuses then inferences must be drawn from this refusal.
