CANNON BALL, N.D. (AP) — Authorities say they will charge Green Party presidential candidate Jill Stein who is accused of spray-painting construction equipment during a protest against the Dakota Access Pipeline in North Dakota.

Morton County Sheriff Kyle Kirchmeier said Tuesday that Stein will face trespassing and vandalism charges.

A spokeswoman for Stein says activists invited her to leave a message at the protest site Tuesday. Stein sprayed ''I approve this message'' in red paint on the blade of a bulldozer.
