Hillary Clinton has earned at least $12 million in 16 months since leaving the State Department, a windfall at odds with her party's call to shrink the gap between the rich and the poor.

Clinton's income since her resignation as secretary of state in February 2013 is derived mostly from her latest memoir, speeches and paid appearances at corporate retreats.

At least 12 organizations that previously booked President Bill Clinton — who has been paid almost $106 million in speaking fees alone since he left the White House — also hired his wife. Among them: Goldman Sachs Group Inc. (GS) and the National Association of Realtors.
