PHOENIX (AP) — Donald Trump was just a few weeks into his candidacy in 2015 when came to Phoenix for a speech that ended up being a bigger moment in his campaign than most people realized at the time. Trump savaged his critics and the media, vowed to fine Mexico $100,000 for each immigrant entering the country illegally, talked tough on trade, promised to return America to its winning ways and borrowed a line from Richard Nixon in declaring, "The silent majority is back." The packed crowd ate it up — the raucous enthusiasm an early sign of the overwhelming support among Trump's base that would help carry him to the presidency.
