The Cowboy Indian Alliance continued their protests against the controversial Keystone XL Pipeline.

Wizipan Garriott Little Elk, a member of the Rosebud Sioux Tribe of South Dakota, and farmer Art Tanderup were nearly arrested for wading into the reflecting pool during a protest at the Lincoln Memorial. They carried a banner that read, "Standing in the water could get me arrested. TransCanada pollutes drinking water & nothing happens."

Events continue today with a prayer vigil outside the home of Secretary of State John Kerry. The State Department is reviewing the permit for the pipeline.

The week culminates with a march from the National Mall to the White House on Saturday to urge President Barack Obama to reject the permit.
