Here are the seven biggest donors to the Bill, Hillary and Chelsea Clinton Foundation

A Washington Post analysis shows that since its creation in 2001, the Bill, Hillary and Chelsea Clinton Foundation has raised nearly $2 billion in cash donations and pledges, a whopping figure that illustrates the Clintons’ global reach.

The review found that there is strong overlap between the family’s political base and the foundation and that a substantial number of the foundation’s largest donors — those who have given at least $1 million — are based outside of the United States. Financial institutions also make up the largest portion of the foundation’s corporate giving.

So who are the foundation’s absolutely largest donors? There are seven contributors who, according to an updated donor list posted to the group’s Web site this month, have given more than $25 million each since they started giving to the foundation. They are:

The Bill & Melinda Gates Foundation: The charity launched by the founder of Microsoft to give his private wealth away is one of the largest and best known nonprofits in the world. It has had a longstanding relationship with the Clinton Foundation, including joining with Hillary and Chelsea Clinton in 2013 to launch an initiative aimed at improving the lives of women and girls.

Frank Giustra, the Radcliffe Foundation: Giustra, a Canadian mining magnate who also founded Lions Gate Entertainment, sits on the Clinton Foundation’s board of directors. The Radcliffe Foundation is Giustra's Vancouver-based charity.

Clinton Giustra Enterprise Partnership: The partnership was launched by Giustra and Bill Clinton in 2007 to spur economic development in some of the world’s most impoverished regions.

Fred Eychaner: A Chicago-based media magnate, Eychaner has also been a major Democratic supporter, giving millions, for instance, to political action committees aimed at helping Democrats winning House and Senate majorities.

Nationale Postcard Loterij: A major lottery based in the Netherlands. Winners are chosen using local residents’ postal codes. The lottery distributes hundreds of millions of dollar each year to dozens of charities around the world. Bill Clinton has served as an appointed ambassador of the organization.

The Children’s Investment Fund Foundation: A major London-based charity that works to eliminate malnutrition and poverty among children in developing countries. It was founded by British hedge fund manager Christopher Hohn and his wife, Jamie Cooper-Hohn.

UNITAID: Based in Geneva, the organization aims to fight HIV/AIDs and other diseases in developing countries. Started in 2006 as a partnership between the governments of Brazil, Chile, France, Norway and Britain, it is funded largely through a surcharge on airline tickets sold in more than two dozen countries.
