A formerly well-connected Republican donor, accused of plying petite, vulnerable teenage girls with cash, liquor and gifts, goes on trial Tuesday on federal charges of sex trafficking minors. Anton "Tony" Lazzaro is charged with seven counts involving "commercial sex acts" with five minors ages 15 and 16 in 2020, when he was 30 years old. His indictment touched off a political firestorm that led to the downfall of Jennifer Carnahan as chair of the Republican Party of Minnesota. His co-defendant, Gisela Castro Medina, who formerly led the College Republicans chapter at the University of St. Thomas, pleaded guilty to two counts last year. She is cooperating with prosecutors and will testify against him. She faces sentencing in August.
