The state attorney general leading the investigation into Exxon Mobil over climate change appears to be shifting gears in a Democratic probe that has suffered from recent pushback in the courts.

Democratic New York Attorney General Eric Schneiderman told the New York Times in a Friday article that he is pursuing a new tack in going after the oil company for not being forthcoming to the public about global warming. It’s a charge that Exxon says is false and has fought in the courts to redact as an affront to free speech.
