The three-times married real estate mogul was among the most vocal, most persistent of the “birthers,” people who insisted Obama’s Hawaii birth details were falsified to cover up his birth in Kenya to an American mother and Kenyan father.

Only people who are U.S. citizens at birth are eligible to be president of the United States.

After the White House released Obama’s long form Hawaiian birth certificate, Trump claimed credit for forcing his hand and still questioned if the document were real. Obama, in turn, dismissed Trump as a “carnival barker.”
