Do you honestly think she has a clue as to what goes on in any of the other committees she's a member of?
No, I don't. And she's not the only one. Most of Congress has no knowledge of science, economics, business, agriculture, the Constitution or anything else that comes before them. They are completely at the mercy of their anonymous staffs and unknown outside lobbyists and cocktail party peer pressure when formulating their positions on issues. Lee's just one of the most visible because she doesn't know how ignorant she is and, so, doesn't know when to keep her trap shut.
I'm guessing the kind of science she advocates is man-made global warming, science fiction “that pale data man is SO smart”, and Scientology
