Columbia University junior Yunseo Chung sued U.S. President Donald Trump and other top officials, challenging “the government’s shocking overreach in seeking to deport a college student… who is a lawful permanent resident of this country, because of her protected speech.”
Well Trump is protected on any of his “official acts” as president, which apparently means anything done while being president
So he’s not on the hook personally, but that doesn’t mean you can’t sue the government for his actions
