Today’s proceedings in the Don Blankenship trial ended as Assistant U.S. Attorney Steve Ruby continued his re-direct examination of former Massey Energy ventilation expert Bill Ross.

Among other things, Ruby was asking Ross about cross-examination that appeared aimed at blaming some of Massey’s problems on coal miners who complained about having to perform work — such as cleaning up spilled coal or rock-dusting — that wasn’t specifically part of their job description.

Ross emphasized that, “I didn’t call anyone lazy,” and that, “it’s the foreman’s responsibility to oversee their activities, to ensure they comply with the law.”

Ruby began questioning Ross again after defense lawyer Bill Taylor completed his cross-examination of Ross.

The jury returns at 9 a.m. on Friday.
