Donald Trump still won't acknowledge President Barack Obama was born in the U.S. and insinuated on Sunday that the country has already had its first Muslim president.<br />The real estate mogul called in to "Meet The Press" Sunday morning to address the ongoing controversy that followed his lack of response after a supporter asked Trump how he would address "a problem in this country ... called Muslims."<br />Host Chuck Todd used the line of question to turn to another tea party stumping point: that the president isn't a U.S. citizen.<br />Trump refused to share his current views on the factually inaccurate sentiment, instead telling Todd he just doesn't like talking about it and "won't talk about it."<br />"I just don't discuss it," the candidate said.<br />"Really, it hasn't been brought up in a long time."<br />Trump is actually one of the forefathers of the Obama birther conspiracy.<br />He made headlines in 2011 after persistently demanding to see the president's birth certificate while raising doubts over Obama's birthplace in Hawaii.
