The Democratic Party of Wisconsin and Yee Leng Xiong, the party’s candidate for state treasurer, are seeking a court order to stop a Trump administration ad campaign they say improperly used taxpayer money to promote the president and attack his critics. The party filed suit Friday, Oct. 9. The ads ran on broadcast television, cable and streaming services and were labeled as paid for by the U.S. government, according to the lawsuit. The complaint alleges they promoted the administration’s actions and criticized Trump’s opponents. Norm Eisen, a co-founder and board member of Democracy Defenders Action, which is representing the plaintiffs with the law firm Hecker Fink, said Monday that the case is one part of a broader legal effort. He argued that pursuing multiple cases could help secure a clear court order blocking the spending. “Using that taxpayer money to pay for political ads is illegal, unconstitutional, and just wrong,” Eisen said during an online news conference. He also said some of the ads were recycled Trump campaign spots with a new government funding label. The lawsuit is among at least three challenges to the campaign. Common Cause and the Democratic National Committee also filed suits last week, and a New York federal judge issued an order Sunday blocking the ads. Eisen said the Wisconsin plaintiffs would join an effort to seek another temporary restraining order at a hearing scheduled this week in Washington, in the DNC’s case. Devin Remiker, chair of the state Democratic Party, said he saw government-funded ads as recently as Sunday during a Green Bay Packers game, despite administration claims that payments for the ads were being shifted from the federal government to a Trump-supporting super PAC. Xiong said he joined the lawsuit to challenge the use of public funds for political promotion. “Our tax dollars should serve the people, not promote a politician,” he said. Eisen said the state party brought its own case because elections are administered at state and local levels as well as nationally. Xiong’s participation also makes the lawsuit a challenge brought by a state party and a state candidate, he said.
