Meanwhile, activists in southeastern Iowa continued a campaign of civil disobedience aimed at stopping the Dakota Access pipeline company from boring under the Mississippi River. On Saturday, members of the Mississippi Stand encampment locked their arms together at the site and halted work for about an hour while police worked to separate them. Later on Saturday, an activist locked herself to the underside of a truck, delaying construction while crews dismantled the vehicle’s axle. Among those arrested over the weekend was Lorenzo Serna, who was filming video for the online news site Unicorn Riot.
