Hillary Clinton releases her 2015 tax return, puts more pressure on Trump to do the same

Bill and Hillary Clinton earned a combined $10.6 million last year, according to a tax return that Clinton's campaign released on Friday.

This latest filing shows that the Clintons paid a federal tax rate of 34.2 percent in 2015. The majority of their earnings comes from speaking fees Hillary Clinton charged before she launched her presidential campaign in April of 2015. She earned more than $6 million from these engagements and the power couple together gave more than $1 million to charity. 

Clinton's Tax Return History:

The Clintons have released tax returns for every year dating back to 1977. Hillary Clinton has been especially diligent in that regard, releasing her returns for the last eight years. 

While not necessarily required to do so as a candidate, almost every presidential nominee since 1976 has made their tax returns public. Clinton's Republican opponent, Donald Trump, has not released his tax returns and has not indicated he will.

Here's Trump submitting his 'yuuuge' tax return.

Trump's response to tax return questions (as compiled by The Daily Show):

• 2011: "If I run, you'll see what a great job, because I'll do a full disclosure of finances. ...Maybe I'm going to do the tax returns when Obama does his birth certificate."
• 2015: "We'll see what I'm going to do with tax returns. I have no major problem with it, but I may tie them to a release of Hillary's emails."
• 2016: "If the audit is finished. I'll do it as fast as the audit is finished."
• 2016: "There's nothing to learn from them."

Obviously, Twitter weighed in. 

Likely reasons why Trump doesn't want to release his returns:

• Trump wants to hide how wealthy he actually is (Trump says he's worth $10 billion, but many other sources, like Forbes, estimate its $4.5 billion)
• Trump doesn't donate as much to charities as he claims he does
• Trump pays extremely little in taxes (income from investments allows one to pay a lower rate than income from a salary)
