Judge will let Exxon question climate-change investigation

A federal judge has opened the way for Exxon Mobil Corp. to seek documents and question witnesses who may help the Massachusetts Attorney General Maura Healey investigate whether the company hid what it knew about climate change.

U.S. District Court Judge Ed Kinkeade in Dallas said Thursday that critical comments Healey made at a news conference raised the possibility that she acted in "bad faith" by issuing a subpoena against the company.

Healey and New York's attorney general have accused Exxon of committing securities fraud by misleading investors and the public about what the company knew about the link between burning fossil fuels and climate change.
