Common Cause et al. v. Department of Homeland Security, et al., Opinion Granting TRO
The Court held that the plaintiffs showed they were being harmed by the ads and were likely to win their argument that the government was using money in an improper way to pay for the ads. It also said the harm was urgent because the ads could still affect voters before the election, and those effects couldn't be undone afterward. And the judge wasn't persuaded by the government's claim that the case was effectively over just because it had started winding the ad campaign down.
