Aid groups helping migrants along the border say they’re dealing with an uptick in harassment from vigilante groups and far-right activists there. Vigilantes have long been part of the fabric of Arizona’s borderlands – especially in remote stretches like Sasabe. But Dora Rodriguez, an aid worker the Tucson Samaritans and Salvavision, says as the number of asylum seekers has increased in places like Sasabe, so have confrontations with vigilante groups. Many arrive armed with rifles, trying to get personal information from migrants and aid workers.
