Here is a partial list of information Trump has promised and never supplied.
I'd love it if the press would hold him accountable for all his endless BS.
Tax returns: At the height of his birther crusade in 2011, Trump offered a challenge to President Barack Obama: if the commander-in-chief released his long-form birth certificate, Trump would put out his tax returns.
tax returns again: In January Trump said on Meet the Press that he would release his tax returns imminently. "We're working on that now," he said. "I have big returns, as you know, and I have everything all approved and very beautiful and we'll be working that over in the next period of time."
Proof he's being audited: Trump promised to release a letter proving that he was under audit. In March, in response to to repeated inquiries and promises to release documentation pertaining to the audit, Trump produced a letter from his lawyer (dated three weeks earlier) saying that his returns from 2009 until the present were under review by the IRS. But Trump's lawyers are paid by Trump. He has not produced any correspondence from the IRS that would confirm an audit was under way.
List of creditors: When NBC News' Lester Holt asked Trump at the first presidential debate why he had not released his tax returns, Trump made a counteroffer: he would release a list of his creditors instead. "I could give you a list of banks," he said. "I would—if that would help you, I would give you a list of banks. These are very fine institutions, very fine banks. I could do that very quickly." Three weeks later, though, Trump has still not released that list.
Secret information in Hawaii: In 2011 Trump claimed to have sent investigators to Hawaii to uncover the truth about Obama's birth certificate, and he said he would release the results of their investigation "at a certain point in time." No grand announcement ever came. "He'll reveal it when the time is right," Tana Goertz, the co-chair of Trump campaign's in Iowa, told MSNBC last summer.
Melania's immigration documents: Following reports that Melania Trump had (illegally) worked in the United States under a tourist visa in the 1990s, Trump vowed to hold a press conference featuring his wife to set the record straight. No press conference ever occurred.
Medical records: In September, as Trump was claiming that Hillary Clinton was in poor health, ABC' News' David Muir asked why he didn't release his own medical records. "I might do that, I might do that," Trump said. "In fact, now that you ask, I think I will do that. I'd love to give full reports." Trump had previously released a one-page letter from his gastroenterologist that was widely dismissed by medical experts as odd and unprofessional, and he later revealed additional medical details (from the same doctor) on Dr. Oz's television show. But Trump has yet to produce a full medical report.
