Trump's speech in Phoenix follows an event in Las Vegas as the candidate draws adoring crowds following his divisive comments about the border and Mexican immigrants.
In Phoenix, a standing-room-only crowd of supporters carried signs reading "Make America Great Again" and "Truth Trumps All."
Trump says he loves Mexican immigrants and that many of those in the country legally work for his companies. But he says American border and trade policy is causing the country to get "ripped" by foreign governments including Mexico and China.
