Cal Robinet, a 37-year-old union electrician, and 14 others were arrested by federal agents in the Twin Cities on June 16 and charged with conspiracy to impede or injure immigration enforcement officers during Operation Metro Surge. The defendants include teachers, union organizers, and transgender rights activists who opposed the massive immigration enforcement operation. The Justice Department has characterized them as members of Antifa, while legal observers have questioned whether the prosecution focuses on crimes or ideology.
