Following a Supreme Court ruling that struck down his executive order altering birthright citizenship, President Donald Trump turned to social media to urge lawmakers to take legislative action. The Court’s 5–4 decision held that the 14th Amendment bars the president from unilaterally changing who receives citizenship at birth, though Justice Brett Kavanaugh noted that Congress could alter the rule through legislation. In a post on Truth Social, Trump responded to the loss by congratulating Chinese leader Xi Jinping sarcastically, then called on Congress to begin work immediately on ending birthright citizenship. The ruling mandates citizenship for children of undocumented immigrants, foreign workers, and government-funded tourists, a policy Trump had sought to overturn via a January 20 executive order.
