FILE - In this April 26, 2010 file photo, Massey Energy Co. Chairman and CEO Don Blankenship attends a news conference in Charleston, W.Va.

Eighteen former Massey Energy officials have refused to testify in the investigation, citing their Fifth Amendment right to avoid self-incrimination, including Blankenship.
