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.

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.

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.
