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.

The Supreme Court hears arguments in Trump v. CASA, Trump v. Washington, and Trump v. New Jersey, a case about judges stopping President Trump's executive order that limits birthright citizenship for children born to undocumented parents.

The Justices on the Supreme Court wrestled on Thursday with a high-stakes case involving birthright citizenship that’s poised to shape both the Trump Administration’s immigration policy and its attempts to expand presidential power.
