A federal judge in New Hampshire has issued a nationwide temporary injunction blocking President Donald Trump's executive order aimed at ending birthright citizenship. The ruling responds to a class-action lawsuit representing children affected by the order, which denies citizenship to those born in the U.S. to undocumented parents. The judge certified the class-action lawsuit, encompassing all children who would be impacted by the ban. Subsequently, a Maryland federal judge indicated she would also block the order nationwide if permitted by an appeals court. Additionally, a coalition of states argued before a Massachusetts federal court that only a nationwide injunction can fully address their legal challenge against Trump's executive order. The legal proceedings continue amid ongoing appeals, with courts considering the scope and jurisdiction over the class-action motions.
