An official familiar with the investigations says New York's attorney general is examining statements by Exxon Mobil and Peabody Energy to determine whether they deceived investors about climate-change causes and impacts.
The official says a subpoena was sent Wednesday to Dallas-based Exxon after a yearlong review of shareholder disclosures. The official wasn't authorized to publicly discuss the probes and spoke to The Associated Press on condition of anonymity.
Attorney General Eric Schneiderman's office sought similar documents on climate change from St. Louis-based Peabody in 2013.
A spokesman for Schneiderman declined to comment Thursday.
An Exxon spokesman tells The Associated Press the company received the subpoena and rejects the allegations it suppressed climate-change research.
Peabody says it continues to work with the attorney general's office regarding its disclosures.
