Per the WSJ editorial

"We have since learned that both the L.A. Times (via a collaboration with the Columbia School of Journalism) and InsideClimate News efforts were partly underwritten by a Rockefeller family charity while Rockefeller and other nonprofit groups were simultaneously stoking Mr. Schneiderman’s investigation."

From ICN's funders page. 

"Donors who support our award-winning environmental journalism do not have access to our editorial process or decision-making. Please be mindful of false reports that suggest otherwise, or that seek to discredit our news organization with misinformation and mischaracterization. "

ICN's real good at hiding it's donors, so good that apparently the geniuses at WSJ just "discovered" them. There's so many things wrong with this editorial that I don't even know where to start.
