More than half of the Clinton Foundation’s major donors would be prevented from contributing to the charity under the self-imposed ban on corporate and foreign donors the foundation said this week it would adopt if Hillary Clinton won the White House, according to a new Washington Post analysis of foundation donations.

The findings underscore the extent to which the Clintons’ sprawling global charity has come to rely on financial support from industries and overseas interests, a point that has drawn criticism from Republicans and some liberals who have said the donations represent conflicts of interest for a potential president.

The analysis, which examined donor lists posted on the foundation’s website, found that 53 percent of the donors who have given $1 million or more to the charity are corporations or foreign citizens, groups or governments. The list includes the governments of Saudi Arabia and Australia, the British bank Barclay’s, and major U.S. companies such as Coca-Cola and ExxonMobil.
