Dot,

Scientists are rubber-necking at the Smithsonian's "Hall of Human Origins." 

The exhibit explains that climate change has nothing to do with man-made pollution and that humans will eventually evolve around the effects of climate change.

David Koch bankrolled the exhibit with $15 million--and he didn't stop there. 

He sits on the Board of the Smithsonian and the American Museum of Natural History, and helped funnel $1.2 million to a climate-denier scientist who's on the Smithsonian's payroll. 

The conflict of interest couldn't be clearer than if it were etched in stone.

Science museums are where people go to learn about the world from top scientists--there shouldn't be any conflicts of interest from oil and gas billionaires. 

But for the Koch Brothers, the Smithsonian and American Museum of Natural History are just another channel to peddle debunked, scientifically inaccurate misinformation about climate change.

Climate-denier David Koch shouldn't be anywhere near these museums’ boards. 

We're joining with the new Natural History Museum, Forecast the Facts, Environmental Action and several other organizations to call on the Smithsonian and the American Museum of Natural History to do the right thing and kick David Koch to the curb!

Tell the Smithsonian and the American Museum of Natural History History to kick David Koch off their board! 

We'll deliver the petition signatures to the American Museum of Natural History and the Smithsonian right before their board meetings, so their leadership knows where the public stands.

Public outcry isn't the only pressure these science museums are feeling over David Koch.

The world's top scientists, including several Nobel Prize winners, signed onto a letter asking that the Smithsonian and American Museum of Natural History cut all ties to the fossil fuel industry.

The Koch Brothers are trying--yet again--to use their gigantic wallets to buy influence without facing any consequences. 

But, thankfully, activists like you and me aren't willing to let them get away with it.

When the Koch Brothers tried to buy-out the Tribune Company newspapers, citizen uproar forced them to back out of the deal. 

When they tried to use PBS to censor the documentary "Citizen Koch," we mobilized activists across the country to air the film and protest PBS until Charles Koch stepped down from PBS's board.

Now, we're aiming the fight at two of the largest science museums in the country. 

The Smithsonian and the American Museum of Natural History should be beacons of knowledge, not a conflict of interest.

Tell the Smithsonian and the American Museum of Natural History History to kick David Koch to the curb!
