YUMA, Ariz. - Protesters have engaged in minor scuffles and shouting matches with President Donald Trump's supporters as hundreds of people line up to get inside his rally in Phoenix.

  

At one point, police officers formed a line in the middle of a street to separate the protesters and Trump supporters. In one exchange, a Trump supporter and protester shoved each other. In another, the two groups shouted at each other before moving on.

  

The line of Trump fans wearing red "Make America Great Again" hats grew longer as the afternoon went on and the temperature soared above 100 degrees.

  

City of Phoenix spokeswoman Julie Watters says the fire marshal has set capacity for the venue at 19,000.
