HOUSTON (Reuters) - U.S. Secretary of State Rex Tillerson, while chief executive of Exxon Mobil Corp, used an alias for emails with employees and board members because his primary account was jammed with too many messages, the oil company said on Tuesday.
New York Attorney General Eric Schneiderman, who is investigating whether Exxon misled shareholders and the public about climate change, wrote to a judge on Monday accusing Exxon of not previously disclosing the alias and Tillerson's climate-change communications through it.
