US District Judge Jennifer Rochon issued the injunction in response to a lawsuit brought by a coalition that includes the advocacy group Common Cause and the Service Employees International Union Local 32BJ. The ads were funded through a $20 million contract from the Department of Homeland Security, first reported by CNBC in late September.
In her order, Judge Rochon found that the plaintiffs' motion was not moot, that they had standing to proceed, and that they were likely to succeed on the merits of the case. She also found they would suffer irreparable harm in the absence of an injunction, that the balance of the equities tipped in their favor, and that an injunction serves the public interest.
The coalition said in a statement that it was pleased the court acted swiftly to prevent more taxpayer dollars from being used for what it called blatantly unlawful political propaganda. It argued there was no legal justification or precedent for the president to use the machinery of government and funds set aside by Congress for other purposes to influence electoral outcomes in his own interest.
The plaintiffs said that as the case moves forward and voters make their voices heard in the election, they would work to ensure the rule of law continues to be upheld and the rights of voters and democracy are protected.
The report was marked as developing news, and no response from the administration had been published at the time of the ruling.
