Hillary and Bill Clinton earn more than $139M between 2007-14, pay tax rate of 31.6 percent

Federal tax returns released by Hillary Rodham Clinton show she and former President Bill Clinton paid an overall 31.6 percent tax rate on more than $139 million the couple earned between 2007 and 2014.

In a statement released by her campaign Friday, the Democratic candidate for president says the couple has paid nearly $44 million in federal taxes since 2006 and donated nearly $15 million to charity.

The Clintons donated nearly 11 percent of their income to charity in 2014. This year, the Clintons boosted personal donations to their global family charity, the Clinton Foundation, to between $5 million and $10 million.

Clinton's statement doesn't comment on her earnings in that time, but the couple earlier reported having earned more than $30 million from speeches and book royalties since mid-2013.
