SALEM, Ore. — Republican gubernatorial candidate Bud Pierce has apologized again for comments he made about the abuse of women during a debate.

On Friday Pierce said successful women aren’t as susceptible to domestic abuse and sexual violence as those on lower economic rungs. His remark drew boos from the audience at the debate at the Portland City Club and Pierce said in a statement later that “sexual and physical abuse is wrong.” Pierce also apologized to Democratic Gov. Kate Brown, who in the debate disclosed that she had been a domestic violence victim.

On Wednesday Pierce posted a video statement on his campaign’s Facebook page. The Salem oncologist said “domestic violence occurs in all economic groups. I apologize for this ignorant and potentially dangerous statement.”

Pierce’s communications director, Stacey Kafka, resigned following Pierce’s original statement during the debate.
