Aspen, Colorado (CNN) -- Attorney General Eric Holder suggested on Thursday that the Justice Department might be focusing beyond BP in its Gulf Coast oil spill investigation.
"We opened a criminal investigation but did not indicate what the subject of the investigation was," Holder told CBS News anchor Bob Schieffer at the Aspen Institute's 2010 Aspen Ideas Festival. "There are a variety of entities and a variety of people who are the subjects of that investigation."
Holder added, "For people to conclude that BP is the focus of this investigation might not be correct."
