White House on Trump 'Muslim' Comments: 'Is Anyone Really Surprised?'

The White House weighs in on the latest Trump controversy.

"Is anybody really surprised this happened at a Donald Trump rally?" Earnest told reporters. "Anybody paying attention to Republican politics isn’t surprised. Offensive views are part of Trump’s base."

After the event, Trump's campaign told ABC News that he had difficulty understanding the question and was referring to mention of training camps. Asked if Trump believed there were camps in the U.S., the campaign said, "Yes.”

“I haven’t seen anybody produce any evidence to substantiate the claim that there are," Earnest responded.

Earnest indicated that President Obama is not personally offended by speculation he is a Muslim, but did express concern that the comments have been used in the past to generate political support.
