The Reverend Jesse Jackson visited the protest camp to deliver some words of support for their cause.
Jackson led the group in prayer, and said the Native Americans opposed to the pipeline have a right to be heard.
He said America can never be whole until Native Americans are treated with justice and fairness.
He also encouraged activists to hold their ground, and ask the U.S. government to intervene and protect their rights.
"There are two sides of history in this struggle here today. One says to protect the right to vote, one says destroy. One says racial justice, gender equality, one says no. One says law and order, one says be fair....We want to better America and stand up," says Rev. Jesse Jackson
The civil rights leader had also said he would stand with pipeline opponents and "if necessary, go to jail with them."
