DES MOINES, Iowa (AP) — The director of the Iowa chapter of the American Civil Liberties Union hired just last year has abruptly resigned. The Des Moines Register reports that Jeremy Rosen announced his resignation late Monday, calling it “difficult news.” Rosen’s last day is Thursday. He was hired in January 2015 to replace Ben Stone, who had served as ACLU of Iowa’s director for 18 years until July 2014.
