In 1994, during his final successful run for Congress, it was reported that Dornan's wife, Sallie, had made multiple allegations of domestic violence against him earlier in their marriage. In 1966, Dornan had been convicted of a domestic violence offense and sentenced to jail time; however, it was unclear whether his sentence had ever been served. After the allegations were made public, Sallie Dornan retracted them, stating that she had made false claims about her husband during a period when she was struggling with prescription drug addiction. The Dornans' five children asserted that their father had not been physically abusive. During the same campaign, Dornan had signs posted at polling places that warned voters in Spanish that they should be prepared to prove their citizenship in order to vote. The signs suggested that immigration officials would be present at the polls. The success of this action was believed to have kept enough Latino voters away from the polls to eke out a victory for Dornan against Mike Farber.
