Massachusetts Congressman Jake Auchincloss’s chief of staff is leaving his office amid an ongoing feud with Congresswoman Marjorie Taylor Greene. According to CBS 12 in Providence, an Auchincloss spokesperson confirmed that Tim Hysom is stepping down effective Friday and will be joining a different congressional office. Hysom has served as the Newton Democrat’s top aide since he succeeded Joe Kennedy III last year. No interim replacement for Hysom was named. Hysom made headlines in June when Greene  revealed Capitol Police had issued an arrest warrant for him after he was repeatedly caught on surveillance camera putting stickers on one of her posters.
