Sen. Heidi Heitkamp, D-N.D., said Tuesday her re-election campaign would retract an advertisement it placed in a series of North Dakota newspapers that identified domestic violence, sexual abuse, and rape victims without their consent, while misidentifying others.

“I deeply regret this mistake and we are in the process of issuing a retraction, personally apologizing to each of the people impacted by this and taking the necessary steps to ensure this never happens again,” Heitkamp said in a statement to the Washington Examiner.
