Among those charged is Treasure Thoreson, a Minneapolis special education teacher who said Homeland Security agents arrived at her home early one morning in June. “I go and I see a woman standing there in office clothes, but with a Homeland Security vest over the top. And I see six more agents standing in my front yard,” Thoreson told NPR. All of those cases involved opposition to federal immigration enforcement.
