Noon:

A federal prosecutor has told jurors that ex-Massey Energy CEO Don Blankenship was the kingpin of a massive conspiracy and had a "band of yes men" at the company.

In closing arguments Tuesday in Blankenship's criminal trial in West Virginia, U.S. Attorney Booth Goodwin said the former executive tried "to violate nearly every law on mine safety in the book."

Blankenship is accused of putting profits ahead of safety in the years before an explosion killed 29 men at the Upper Big Branch mine in southern West Virginia in 2010.

He could face up to 30 years in prison on charges of conspiring to break mine safety laws at Upper Big Branch and lying to financial regulators and investors about company safety.
