Cowboys and Indians join forces to protest Keystone XL (photos)

Members of the Cowboy and Indian Alliance descended on Washington, D.C. Tuesday to protest the Keystone XL pipeline. The group of ranchers, farmers and indigenous leaders set up an unusual display, building a teepee encampment on the National Mall and riding horses past the Capitol to oppose the border-crossing pipeline. Keystone XL has been mired in political debate as it awaits approval from the Obama administration, which recently announced another delay in the review process.
