Billionaire supports reported inquiry into possible ExxonMobil cover-up

Activist Tom Steyer's comments followed reports that California attorney general is looking into what the world's biggest oil company knew about climate change

Billionaire environmental activist Tom Steyer spoke out on Wednesday in support of an unconfirmed investigation by California into allegations that ExxonMobil spent decades lying to investors and the public about its knowledge of climate change.

"We don't have the facts yet, but I think that there is enough that has been revealed that it's totally appropriate that (California) be conducting this investigation," Steyer told the Guardian. "Anybody who puts out intentionally misleading information I think should be answering to us."
