MARCH 29--Though Donald Trump has yet to release his actual birth certificate, a tantalizing clue emerged today that may indicate the multimillionaire developer was, in fact, born in the United States, The Smoking Gun has learned.
Trump, who has challenged President Barack Obama to prove he is an American citizen, yesterday released what he claimed to be his own birth certificate (“It took me one hour to get,” he crowed).
Except
the document Trump proffered was not an official New York City birth certificate, but rather a document purportedly produced by Jamaica Hospital, where Trump was reportedly born in June 1946.
In an attempt to track down proof of the 64-year-old Trump’s citizenship, TSG today traveled to the main branch of the New York Public Library, which houses a collection of microfiche indices to New York City births. The microfiche cards contain the official Department of Health ledgers of births, broken down by year and borough.
