Did Donald Trump Leak His Own Tax Returns?

• Trump's personal attorney attacks Joe Scarborough after MSNBC host says Trump leaked tax return

• Did Donald Trump leak his own tax returns? Many pundits believe he did and here's why 

Alan: No one knows if Trump released his own tax returns. 

If he did, no one knows if his leaked returns are authentic. 

On this latter point Trump could request that the IRS confirm their validity - rather like Obama releasing his long-form birth certificate which the Hawaiian registrar's office confirmed.

With this in mind, it would have been advantageous for Donald to release ten year old tax returns that represented an atypical year when Trump did pay a sizeable amount of federal tax (although he paid it at a 20% discount to the tax rate paid by middle class Americans).

Excerpt: Urging major tax changes, Buffett has repeatedly said he pays a lower tax rate than his secretary and other employees.

• In 2007, Buffett told NBC Nightly News that he pays a smaller tax rate than multiple employees in his office.
• In 2011, Buffett wrote an op-ed in the New York Times called "Stop Coddling the Super-Rich." In the article, Buffett said that his taxes amounted to "only 17.4 percent of my taxable income — and that’s actually a lower percentage than was paid by any of the other 20 people in our office."
• In 2013, he told CNBC that while his tax rate rose 8 to 9 points more that year, "The differential between me and the rest of the office, not just my secretary but the rest of the office, was greater than that. It'll be closer, but I'll probably be the lowest-paying taxpayer in the office."
