Open Letter to President Obama and Former Governor Romney: Defend America Against Keystone XL

Dear President Obama and Governor Romney,As candidates for president, you both support construction of the southern (OK-TX) leg of Keystone XL, a pipeline that would transport tar sands through the Great Plains from Montana to refineries in Texas.We call on you to withdraw your support for this project in light of the overwhelming evidence, available to both of you, that Keystone XL threatens America’s economy, public health, and national security.
