The Supreme Court’s decision in the birthright citizenship case is “a monumentally terrible decision,” says author Peter Schweizer, whose latest bestseller exposed China’s efforts to exploit birth tourism on an industrial scale. In Trump v. Barbara, The Court this week threw out President Donald Trump’s executive order to federal immigration agencies not to automatically grant citizenship to every child born to a foreigner on US soil. The decision, although expected by many, is absolutely terrible for American sovereignty, Schweizer believes.
