U.S. Senator James Inhofe (R-Okla.), Ranking Member of the Senate Environment and Public Works Committee, today released an updated comprehensive investigation into the financial and political activities employed by charitable and environmental organizations claiming to be non-partisan.

The report begins:

Partisan Environmental Groups Senate Floor Statement
by U.S. Sen. James M. Inhofe (R-OK) September 20, 2008

Mr./Madam President, I rise today to shed some light on a subject that is very important to me, as an American citizen, and as the Ranking Member of the Environment and Public Works Committee.

The situation I’m about to discuss reminds me of an old saying: beware of wolves dressed in sheep’s clothing.

Today’s so-called environmental movement can be described in much the same way. Campaigns to “save the cuddly animals” or “protect the ancient forests” are really disguised efforts to raise money for Democratic political campaigns.

Sen. Imhofe then goes on to explain how each of several environmental groups claiming to be non-profit and non-partisan under IRS. Sec. 501 (c) 3 are actually conduits for contributions to the Democrat Party.

Some of the groups mentioned include:

The Sierra Club
The League of Conservation Voters
National Resources Defense Council
Environmental Defense Fund
The Heinz Foundations
The Pew Charitable Trusts

These groups should surely lose their tax-exempt status since they are clearly not non-partisan.
