No, that's false. -- Your attempt at the character assassination of Turley fails here.
Jonathan Turley is leading a lawsuit against the United States for hiding evidence of uncontrolled burning of dioxins and other carcinogens at Groom Lake. This lead to the deaths of several workers at the Area 51 site.
Of course, the Govt. needs to cover this up because it might release classified information about the UFOs at Groom lake.
