KANSAS CITY, Mo. (AP) – Police say they used pepper spray twice outside a Trump rally in Kansas City, Missouri and two people were arrested for refusing to follow the law.

In a Twitter post late Saturday, Kansas City police did not say if the use of pepper spray was on demonstrators or Trump supporters. Television images showed one protester rubbing his eyes and saying that he had been sprayed.

While a boisterous group of protesters gathered outside the theater where Trump spoke in downtown Kansas City, the event concluded without significant incident. Police say the majority of people exercised their rights to gather peacefully.

Trump’s remarks were interrupted about a dozen times by protesters who managed to get into the theater, and they were escorted out.
