>> And while we're at it, we would like to see those tax returns wouldn't we?>> Hillary Clinton putting her money where her mouth is, releasing her tax returns Friday, and blasting rival Donald Trump in a video for not yet doing the same.>> For the last 30 or 40 years, every candidate for president has released their tax returns, and I think Donald Trump should, as well.
>> Political correspondent Amanda Becker>> The Clintons and other critics of Donald Trump including some Republicans have called on him to release his returns. They say it will give valuable insight into what his business ties are, his investments, and other things that could prove to be problematic if he was leading the country.
>> His casual suggestion that->> Clinton in the past has gotten flack for her high speaking fees. US Senator Bernie Sanders said, she really shouldn't have been cozying up to Wall Street banks by accepting really big speaking fees for appearing there. Of course, this year's return showed that, that speaking income has dropped off significantly, because she stopped giving those speeches once she became a candidate.
>> In 2015, Hillary and her husband former president Bill Clinton paid a federal tax rate of 34.2% on an income of about $10 million. The Clintons have made the returns public in some form every year since 1977, but Becker says the most interesting thing about this filing was the amount they earned in wages.
>> So one thing that was really striking about the Clintons' tax return is that unlike most Americans, virtually none of their income comes from wages or a salary. Just $100 out of more than $10 million they actually earned as a result of wages. About half of the more than $10 million that the Clintons' reported in income on their tax return last year, came from speaking fees that former president Bill Clinton got over the course of that year.
>> Clinton's running mate, Virginia State Senator Tim Kaine and his wife, who also released their returns Friday, paid a federal tax rate of 20.3% last year. According to Politico, Trump paid zero to very little taxes for two years in the 1990s. And some speculate, not much has changed since then.
