A candidate running for Illinois attorney general was robbed at gunpoint while he was taking promotional photos for his campaign Thursday afternoon in the Northwest Side ward where he’s also the Democratic committeeman, according to his campaign manager and authorities. Aaron Goldstein, 42, and several members of his campaign team were in the middle of taking publicity shots when the robbery happened, according to Goldstein’s campaign manager. The robbery took place about 3:25 p.m. in the 4600 block of North Albany Avenue in Albany Park, when three men in their early 20s approached them, according to a law-enforcement source. One of the men flashed a handgun and demanded the camera equipment and other personal belongings from the team, according to police.
