Environmental groups on Wednesday said they will not comply with subpoenas issued by House science committee Republicans targeting a probe by Democratic state attorneys general into Exxon Mobil.

The anti-fossil fuel group 350.org and Greenpeace USA said the Republicans’ subpoena, issued by Science Committee Chairman Lamar Smith, R-Texas, is the “latest attempt by Exxon’s congressional allies to chill the work of climate justice organizations to hold Exxon and the fossil fuel industry accountable for their decades of climate deception.”
