Exclusive: Billionaire green activist Steyer says not yet ready to back Clinton, open to Sanders

Reuters reports:

Billionaire environmental activist Tom Steyer said he is not yet prepared to back Hillary Clinton as the Democratic nominee for president and he would not rule out supporting her main rival, Bernie Sanders, if he beats her in the primaries.

One of the biggest Democratic donors, Steyer could help Clinton boost her standing among environmentalist activists who are a key constituency within the Democratic party. Clinton is locked in tight races with Sanders in Iowa and New Hampshire, which both have early nominating contests.

"Our real goal has been not to support any one candidate, but to emphasize and highlight the issue (of climate change) so that the candidates can lay out their solutions and so the American people can have a chance to make a decision," Steyer said in a telephone interview on Tuesday.
