PORTLAND — The Oregon Nurses Association has accused Secretary of State Dennis Richardson of having a conflict of interest in a proposed ballot measure to repeal a health care tax plan.

The association has asked to Richardson, who oversees all statewide elections, to disclose any and all political and financial ties he has with Rep. Julie Parrish, R-West Linn. Parrish is spearheading the repeal initiative and is a political consultant paid by the Richardson campaign. The association also demanded that Richardson recuse himself from any business involving the proposed repeal.
