The U.S. Supreme Court on Friday will hold a hearing on the ban of TikTok, which carries implications on the global marketplace, technology, freedom of speech and national security.

The justices are expected to rule quickly in the case, which pits national security concerns about China against the First Amendment’s protection of free speech.

The Supreme Court agreed to fast-track TikTok's request for review, and the Supreme Court hearing comes just nine days before a U.S. ban takes effect.
