A case focused on birthright citizenship could come later, but the bulk of the argument is expected to concern whether a single judge can freeze a policy nationwide.

The Trump administration will begin arguments Thursday before the Supreme Court to challenge the Fourteenth Amendment to the U.S. Constitution, which guarantees anyone born in the United States is granted citizenship.

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.
