Apr 01, 2026; Washington, DC, USA; Mike Martin of Springfield, Va. joins a rally outside the US Supreme Court as the court hears Trump v. Barbara in Washington, DC, on April 1, 2026. The court is reviewing a lower court's rejection of Trump’s argument that children of parents who are in the country illegally or temporarily are not entitled to citizenship.
