ANOTHER CULTURE-OF-CORRUPTION COVERUP? House panel wants enviro activist group’s communications with EPA’s McCarthy. “A House committee investigating the destruction of more than 5,000 official cellular telephone text messages by the Environmental Protection Agency wants a major nonprofit activist group to provide copies of all its communications with Gina McCarthy, the agency’s chief, on the proposed Keystone XL pipeline. . . . Karpinski’s group has received nearly $90 million in 1,056 contributions since 2000 from liberal philanthropies and individuals, including the Tides Foundation. Tides pioneered the use of an umbrella foundation of wealthy individuals wishing to remain anonymous to funnel millions of dollars in ‘dark money’ to their favored causes.”
