PORTLAND, OR – Oregon state treasurer and Portland mayoral candidate Ted Wheeler Wednesday took the People’s Pledge, declaring his opposition to special interest groups trying to tilt the outcome of the election via outside campaign spending.

The Pledge, modeled on that taken by U.S. Senator Elizabeth Warren in her race against Scott Brown, puts the candidates formally on record opposing independent expenditures by PACs or other independent organizations – practices akin to those used by SuperPACs and “dark money” issue groups.

Wheeler today pledged that if a committee or organization spends money on an independent expenditure for television or Internet advertising on his behalf or against an opponent on his behalf, he will donate 50% of the cost of that advertising towards select charities. Wheeler challenged all other candidates to do the same.

“This agreement puts into writing what I promised the day I launched may campaign to be the next mayor of Portland. I’m committed to an open and transparent government, one that will not be influenced by powerful outside interests – this is how I put action behind my words.”

Wheeler has established a long record of advocating for open and transparent campaign finance. He was the first state treasurer to call upon the Securities and Exchange Commission to make disclosure of political contributions mandatory for publicly traded corporations, a proposal that generated more than one million comments to the federal agency.
