An executive at one of Steyer’s nonprofit groups and a political vendor who has received hundreds of thousands of dollars from the hedge fund manager’s political operations helped run the group, which is accused of influencing state energy policy through undisclosed payments to Oregon’s first lady.

The controversy centers on Gov. John Kitzhaber’s fiancée, Cylvia Hayes. She was paid $118,000 by the Clean Economy Development Center (CEDC) to advocate for environmentalist policies in Oregon.

Hayes never disclosed those payments, despite acting as an informal adviser to the governor as he pushed a low-carbon fuel standard for the state.

Dan Carol, then a strategic adviser to CEDC, helped Hayes land the position. He was given a $165,000-per-year job in the Kitzhaber administration.

Kitzhaber is expected to resign today under intense scrutiny over the scandal. The scandal could extend beyond Oregon given Steyer’s involvement. Steyer has donated millions to a group that helped finance Hayes’ position, which could ensnare one of the Democratic Party’s most prominent fundraisers in the scandal.

Hayes was reportedly a fellow at the CEDC in 2011 and 2012, but as of late as August of last year, she was still listed on a since-deleted page of its website.

Also listed on that page was Kate Gordon, a member of the CEDC’s board. Gordon leads the energy and climate division of Next Generation, an environmental nonprofit group founded by Steyer.

Another director of the group, according to the website, was Mike Casey. Casey runs a media and public relations firm called Tigercomm that does polling and advertising work for Steyer’s Super PAC, NextGen Climate Action.
