ExxonMobile, one of the largest and most powerful companies in the world, is facing mounting calls for a federal investigation of its role in promoting climate-change skepticism. On Thursday, Hillary Clinton joined fellow presidential candidates Bernie Sanders and Martin O’Malley, along with a number of members of Congress, in calling for an inquiry. “Yes, yes. They should,” Clinton said when asked at a campaign event if she’d ask the DOJ to launch a probe. “There’s a lot of evidence that they misled…people.”

Though Clinton has tried to stake out an ambitious climate platform (which is not without critics), it’s somewhat significant that she joined her competitors in calling out Exxon, specifically. Some of the company’s lobbyists and lawyers have raised or donated money to Clinton, including Exxon’s vice president of government relations, Theresa Fariello. Clinton is the only Democratic candidate that has not pledged to reject campaign contributions from fossil-fuel interests.
