Justice Kagan blasted U.S. Solicitor General John Sauer on the birthright citizenship executive order— which she noted has yet to succeed in any federal court, including cases heard by Trump-appointed judges.

Supreme Court Justice Elena Kagan ridiculed President Donald Trump’s challenges to judicial injunctions and birthright citizenship on Thursday, telling the administration it has its strategy all wrong.

In a case involving changes to birthright citizenship, the justices heard arguments on whether a single federal judge in a single district can block Trump administration policy across the country.
