CNN Money reports veteran journalist Mark Halperin sexually harassed women while he was in a powerful position at ABC News, according to five women who shared their previously undisclosed accounts with CNN and others who did not experience the alleged harassment personally, but were aware of it."During this period, I did pursue relationships with women that I worked with, including some junior to me," Halperin said in a statement to CNN Wednesday night. "I now understand from these accounts that my behavior was inappropriate and caused others pain. For that, I am deeply sorry and I apologize. Under the circumstances, I'm going to take a step back from my day-to-day work while I properly deal with this situation."
