A North Dakota county has issued a warrant for the arrest of Green Party presidential candidate Jill Stein, who is accused of spray-painting construction equipment during a protest against the Dakota Access pipeline.
Stein was charged Wednesday in Morton County with misdemeanour counts of criminal trespass and criminal mischief.
A spokeswoman for Stein said Tuesday that activists invited her to leave a message at the protest site, and Stein sprayed "I approve this message" in red paint on the blade of a bulldozer.
The Standing Rock Sioux Tribe is trying to stop construction of a section of the pipeline that tribal leaders say would violate sacred and culturally sensitive grounds and possibly pollute water.
