September 18, 2015 – Washington (CNN)—Donald Trump hit presidential campaign turbulence Friday for his handling of a town hall participant’s comment about President Barack Obama’s religion — but this was only the most recent time the real estate mogul stirred controversy over the President’s background.
Trump has long been one of the most vocal skeptics about Obama’s birthplace and faith.
Four years ago, Trump mounted a campaign to pressure Obama to release his long-form birth certificate, even saying he would send investigators to Hawaii to find out the truth. The effort helped fuel the so-called “birther” conspiracy theory that held that Obama was born in Kenya — and Trump also floated the idea that Obama’s birth documents may label him a Muslim.
“He doesn’t have a birth certificate. He may have one, but there’s something on that, maybe religion, maybe it says he is a Muslim,” Trump told Fox News in 2011. “I don’t know. Maybe he doesn’t want that.”
His accusations reached such a high decibel level that in April 2011, Obama appeared in the White House briefing room to denounce Trump and release the long-form version of his birth certificate.
