Colleen Fagan

Observers who take video of federal immigration operations say agents are recording their faces and license plates.

Colleen Fagan in Portland, Maine, filmed this exchange between herself and a federal agent last month after he seemed to record her license plate.

And now you're considered a domestic terrorist, the agent said.

Fagan has joined a federal class action lawsuit asking a judge to stop DHS from tracking observers and retaliating against them.

DHS told NPR there is no database of domestic terrorists run by the agency, and its methods follow the U.S.

Constitution.
