into other places to try to place the pipes. protesters hugged, held hands and they cheered. they celebrated that this time, this direct action worked. their voices were heard. they won. or at least we can tell you they won for now. the pipeline builder is saying they are committed to that original plan, that they will complete construction of the pipeline without rerouting it and in 45 days, you know this, the u.s. will get a new president, one who says currently he supports this pipeline and he could easily try to have the decision reversed made by the u.s. army corps of engineers which is part of the government. there were more protesters today gearing up for the fight that lays ahead. and the chairman of this tribe, dave archambault says he knows it's not over but told protesters it's time for them to go home now, that their purpose has been served. and we can tell you, he will be on "the last word with lawrence o'donnell." whether they go home or maintain their ground for now, they wait. inauguration is 45 days away and the clock is ticking.
