A campaign finance complaint filed with Portland, Multnomah County and Oregon elections officials alleges that three political committees violated disclosure rules while financing a recent billboard campaign targeting Portland City Councilor Mitch Green and supporting Multnomah County chair candidate Julia Brim-Edwards. Seth Woolley, a software engineer and elections watchdog, filed the 182-page complaint on Oct. 5. It lists 15 potential violations involving the committees DitchMitch, goPDX and fix multCo, and asks officials to investigate whether the committees concealed the campaign’s original funding sources or failed to report expenditures on time. The complaint says United for Portland Action Fund, a political action committee aligned with the Portland Metro Chamber, supplied the money for the billboards. State disclosure records cited in the filing show no other entity contributed to the campaign. The billboards criticizing Green refer to his late payment of a property tax bill and his violation of a backyard burn ban. Another promotes Brim-Edwards as a candidate for Multnomah County chair. Woolley alleges United for Portland created the three committees to add layers between the funder and the advertising. The complaint says the committees used the same administrators and advertising vendor, and that goPDX distributed $156,000 of $160,000 in contributions among the other committees and a consultant. Records show United for Portland transferred $100,000 to goPDX on Sept. 11. That day, goPDX sent $50,000 each to DitchMitch and fix multCo. United for Portland sent another $60,000 to goPDX on Sept. 24; the next day, goPDX reported $6,000 to consulting firm The Rally Point and $25,000 to each of the other committees. Woolley also asks the state to examine differing dates and check numbers associated with the $60,000 transfer. The complaint further alleges that at least one billboard appeared before the committees registered or reported transactions. A DitchMitch sign on Beaverton Hillsdale Highway was visible as early as Sept. 7, according to the filing. State records show the committees’ statements of organization became effective Sept. 14, while their earliest reported transactions were dated Sept. 11. Oregon requires political committees to file a statement of organization within three days of receiving a contribution or making an expenditure, and requires disclosure of who paid for campaign materials and services. The complaint identifies alleged violations of city, county and state rules and asks each jurisdiction to investigate. Portland and Multnomah County elections offices confirmed receiving the filing. The Oregon Secretary of State’s office had not confirmed receipt as of Oct. 6. The potential consequences depend on what investigators find. Untimely reporting can result in civil penalties, while intentionally concealing the original source of funds could carry more serious consequences under state law, including a possible Class C felony charge. The complaint says such penalties could apply to committees and individuals involved; no findings of wrongdoing have been announced. Kyle Prosen, treasurer for DitchMitch, fix multCo and goPDX, declined to comment on the complaint. He previously said he contacted United for Portland after learning about its work and agreed to participate in the committees. United for Portland executive director Doug Moore and Metro Chamber representatives did not respond to earlier requests for comment. Green is seeking reelection in City Council District 4. The billboard campaign comes amid a broader effort by well-funded political groups to challenge progressive Portland incumbents. The allegations remain unproven, and the complaint now puts the committees’ funding and reporting practices before local and state elections officials.
