"Just one spill near the tribe's reservation could release thousands of barrels of crude oil contaminating the tribe's drinking water"
FALSE!
The pipeline has spent millions to relocate the intake pipe for the reservation way upstream from where the oil pipeline will be buried crossing the river, which is NOT on tribal land, but owned by the State and Federal Government.
I like Tulsi too, but this time she is chosing the wrong side, and her facts are incorrect.  She will end up looking silly.
