Trump alleges former Miss Universe starred in sex tape

On Friday, Donald Trump’s campaigning began long before he reached President Gerald Ford's Michigan tomb, where he was slated to speak. He unleashed a slew of early morning tweets maligning Alicia Machado, a former Miss Universe he had previously mocked for her weight, and alleging she had starred in a sex tape. Hillary Clinton called his online commentary “unhinged.” Hari Sreenivasan reports.
