US Supreme Court divided over judges' power in citizenship case22 hours ago Share Save Bernd Debusmann Jr and Kayla Epstein BBC News Share SaveWatch: Should judges be able to block Trump on birthright citizenship? The case asks whether lower court judges should be able to block presidential orders for the entire country - as they have done in this case. There was questioning of lower courts' power to block a presidential order nationwide. And the justices also considered the merits of the birthright citizenship order itself - which critics argue violates the 14th Amendment of the US Constitution and Supreme Court precedent. Justice Samuel Alito, one of the court's most prominent conservatives, appeared critical of the lower court's power to issue nationwide injunctions.
