At a campaign rally in Mesa, Arizona, today, Donald Trump, discussing reports that several asylum seekers in Norway had images of ISIS flags on their cell phones, wondered how the refugees got access to mobile phones in the first place.

“First of all, why are people in a migration having cell phones?” Trump asked. “It’s sort of strange. Who’s paying for those cell phones? Where are they coming from? Who are they calling? These are people — can you imagine, many, many, many cell phones. Where do they get cell phones? Who pays their monthly bill?”

One woman in the crowd incessantly shouted, “Obama!”

Trump also declared that Syrian refugees in the U.S. are “all going back” if he’s elected president.

This led him to claim that he has the support of a majority of Hispanic voters because they don’t want to be “overrun by people pouring across the borders.”
