"Five environmental groups filed a lawsuit against the Department of Homeland Security (DHS) on Tuesday for using tear gas at the protests in Portland, Ore.
The American Civil Liberties Union (ACLU) of Oregon and others represented the environmental groups that filed the lawsuit accusing the agency of deploying “an unprecedented amount of dangerous chemical weapons” without first checking the potential environmental impacts.
The groups allege that DHS violated the National Environmental Policy Act by failing to examine the effects of the chemicals on the environment before using them against protesters demonstrating against racial injustice and police brutality."
