The co-author of the best-selling book "Game Change" told CNN Wednesday night that he's "deeply sorry" and is taking a "step back" from day-to-day work to deal with the situation. He's currently an analyst for NBC News.
His statement came after CNN reported allegations that Halperin propositioned, fondled and pushed himself against five women in the early 2000s while he was ABC News' political director.
The women, who asked to remain anonymous, said they didn't report Halperin's conduct because they feared retribution or were embarrassed.
