Cards Against Humanity sued SpaceX yesterday, alleging that Elon Musk’s firm illegally took over a plot of land on the US/Mexico border that the party-game company bought in 2017 in an attempt to stymie then-President Trump’s attempt to build a wall.

“As part of CAH’s 2017 holiday campaign, while Donald Trump was President, CAH created a supporter-funded campaign to take a stand against the building of a Border Wall,” said the lawsuit filed in Cameron County District Court in Texas. Cards Against Humanity says it received $15 donations from 150,000 people and used part of that money to buy “a plot of vacant land in Cameron County based upon CAH’s promise to ‘make it as time-consuming and expensive as possible for Trump to build his wall.’”
