The Democratic National Committee sued President Donald Trump and his administration in federal court in Washington on Wednesday, alleging the government improperly used taxpayer money to run advertisements promoting the president ahead of the midterm election. The DNC’s complaint says the ads continued to air at public expense even after Trump said Monday that his super PAC, MAGA Inc., would pay for them going forward. The committee is asking the court to block the government-funded advertising, according to the filing. The lawsuit says millions of dollars set aside for the ads remained unspent with fewer than 30 days before the election. The DNC called the spending an effort to benefit Republicans and argued that public resources should not be used for partisan campaigning. “Donald Trump doesn’t get to turn the federal government into his personal campaign operation,” DNC Chair Ken Martin wrote in a social media post Wednesday, describing the spending as an abuse of power. The claims are allegations in a lawsuit; the filing does not establish that the administration violated the law. The information available about the case did not include a response from the White House or details of a court ruling. The dispute puts the use of public funds for political messaging before voters and the court as the midterm campaign enters its final weeks.
