Fellow GOP presidential candidate Donald Trump came under fire this weekend when he didn't correct an audience member at a campaign event who claimed the president was a Muslim who was not born in the United States. Many presidential candidates -- Democrat and Republican -- criticized him for the incident.
On Saturday, Trump defended himself on Twitter saying that he wasn't "morally obligated to defend the president every time somebody says something bad or controversial about him." He reiterated his defense during his remarks at the GOP Iowa Faith and Freedom Coalition event that night.
