Warren Buffett, under audit, releases personal tax information to make things awkward for Donald Trump

My 2015 return shows adjusted gross income of $11,563,931. My deductions totaled $5,477,694, of which allowable charitable contributions were $3,469,179. All but $36,037 of the remainder was for state income taxes.The total charitable contributions I made during the year were $2,858,057,970, of which more than $2.85 billion were not taken as deductions and never will be. Tax law properly limits charitable deductions.My federal income tax for the year was $1,845,557. Returns for previous years are of a similar nature in respect to contributions, deductions, and tax rates.I have paid federal income tax every year since 1944, when I was 13. (Though, being a slow starter, I owed only $7 in tax that year.) I have copies of all 72 of my returns and none uses a carryforward.Finally, I have been audited by the IRS multiple times and am currently being audited. I have no problem releasing my tax information while under audit. Neither would Mr. Trump — at least he would have no legal problem. [Warren Buffett via Bloomberg]
