SCOTUS to rule on Donald Trump's birthright citizenship order

• The Supreme Court will review the constitutionality of President Trump's birthright citizenship order.
• The order states children born in the U.S. to undocumented or temporary residents are not American citizens.
• Lower courts have consistently ruled Trump's order unconstitutional, citing the 14th Amendment.
• Arguments are scheduled for spring, with a final ruling anticipated by early summer.
• The case challenges over 125 years of understanding regarding the 14th Amendment's citizenship clause.

Why It Matters: This ruling could redefine US citizenship for children born in the country.
