Donald Trump’s history of toying with a presidential run

For years, talking about running for the presidency has been somewhat of a hobby for Donald Trump. The first time was in 1987, when, instead of buying ad space to promote his new book, he gave speeches hinting at the possibility of a run. In 2000, he suggested to Larry King that Oprah Winfrey would be his first choice for a vice president. Gwen Ifill traces his trajectory to the nomination.
