Judicial Watch is turning its attention to whether government scientists purposely manipulated global warming data.

The conservative watchdog group is suing the Department of Commerce for communications by the National Oceanic and Atmospheric Administration regarding a study that has been investigated by Rep. Lamar Smith, R-Texas, chairman of the House Science, Space and Technology Committee. Judicial Watch has recently gained headlines for investigations in the Benghazi attack and the Fast and Furious firearms scandal.
