Supreme Court rules on congressional districting

Story highlights

Constitutionality of President Trump's actions will likely be decided by Supreme Court

A lone justice can tip the balance on civil rights, law and corporate regulation

(CNN) —  

On Tuesday night, US President Donald Trump revealed his nominee for the Supreme Court.

Neil Gorsuch, a 49-year-old federal appellate judge from Colorado, is Trump’s pick to replace conservative Justice Antonin Scalia, who died suddenly last year.

Gorsuch will likely face a blistering confirmation battle as Senate Democrats prepare to potentially filibuster Trump’s nomination in the wake of successful Republican obstruction of President Obama’s nominee last year.

While the Supreme Court usually rules on domestic issues of national importance, some cases – such as the 2000 Bush v. Gore decision on the rightful winner of the US election – can have huge international ramifications.

The court may be asked to rule in the near future on Trump’s hugely controversial immigration ban which affects millions of people from Muslim-majority countries.
