In July 2005, Massey Energy CEO Don Blankenship sued Manchin, alleging that Manchin had violated Blankenship's First Amendment rights by threatening increased government scrutiny of his coal operations in retaliation for Blankenship's political activities. Blankenship had donated substantial funds into campaigns to defeat a proposed pension bond amendment and oppose the reelection of state Supreme Court Justice Warren McGraw, and he fought against a proposed increase in the severance tax on extraction of mineral resources. Soon after the bond amendment's defeat, the state Division of Environmental Protection (DEP) revoked a permit approval for controversial new silos near Marsh Fork Elementary School in Raleigh County. While area residents had complained for some time that the coal operation there endangered their children, Blankenship claimed that the DEP acted in response to his opposition to the bond amendment.
